The West-Facing Bay Platforms At Reading Station
Reading station has three west-facing bay platforms, numbered 1, 2 and 3.
They are used as follows.
- Platforms 1 and 2 for local services to Basingstoke, Newbury and Bedwyn.
- Platform 3 for Cross Country reversing trains.
Whilst I was at Reading yesterday, a Cross Country train reversed in a higher numbered platform.
These are some pictures of the bay platforms.

Note that the electrification gantries are in place across the three tracks.
The Platforms From Ground Level
Platforms 1, 2 and 3 At Reading Station
Note how good the access is to the platforms. To the right of Platform 3, is platform 7, which is used for Down trains for the Berks and Hants route and for reversing Cross Country services.
So passengers arriving on a Cross Country train from say Manchester to Bournemouth or Newcastle to Southampton train on Platform 7 have these choices if they need to change trains.
- They could walk across from their train to a local service from platforms 1, 2 or 3.
- They could walk to the other end of the platform and get a local train from the east-facing platforms 4, 5 or 6.
- They could use lifts or escalators to cross the massive bridge to get a train on the Great Western Main Line to London or the West.
- They could also walk across to local services or in future, Crossrail to London.
And of course, they could walk out of the nearby station entrance and get a bus, taxi or their own transport.
Is there a station in the UK, where changing trains comes with so less hassle?
Ready For The Electrification
Looking Back At The Buffer End Of The Bay Platforms 1, 2 And 3 At Reading Station
Note that the gantries seem to have been designed into the station and are ready for the wires, with a nice secure steel plate to which to bolt them.
I can’t see the Heritage Taliban arguing about this design of catenery.
The Length Of The Platforms
Platform Length Of The Bay Platforms 1, 2 And 3 At Reading Station
Note the three-car diesel multiple unit in the platform. I haven’t measured the platform, but I think they are long enough for a five car Class 800 train.
Future Use Of The Bay Platforms
At I said earlier the three platforms are used for local services to Basingstoke, Newbury and Bedwyn and reversing Cross Country trains., but there are two major purposes for which the bay platforms might be used.
The Test Track for Class 800 Trains
When the electric track between Didcot and Reading has been energised, it will be used as a test track for the new Class 800 trains. This article from the Witney Gazette gives more details.
The first three trains are due to be shipped to the UK early next year to begin an extensive test programme, which will include high-speed running on the line between Didcot and Reading once the installation of overhead electric power cables is completed later next year.
Roger Ford in the April 2016 Edition of Modern Railways said this.
Energisation for test running is now scheduled for September this year.
So will one of the bay platforms be used to reverse the train?
I’ve no idea! But the showman in me, would certainly do it, just for the publicity it would generate!
On a serious side, tests could also be performed on the train/platform/passenger interfaces.
Charging Platforms for IPEMUs
Great Western Railway would probably want to get their Class 387 trains into revenue service as soon as possible.
In the September 2015 edition of Modern Railways, there is an article entitled Class 387s Could Be Battery Powered. This is said.
Delivery as IPEMUs would allow EMUs to make use of as much wiring as is available (and batteries beyond) while electrification pushes ahead under the delayed scheme, and in the longer term would allow units to run on sections not yet authorised for electrification, such as Newbury to Bedwyn. The use of IPEMUs might also hasten the cascade of Class 16x units to the west of the franchise.
To run IPEMUs from Reading to Bedwyn or Basingstoke, would need them to be charged.
These bay platforms would be ideal for charging the trains and would mean that Basingstoke, Bedwyn and Newbury would get electric shuttles to Reading.
Conclusion
The team that designed Reading station, deserve a few gold stars.
Electrification At Didcot Parkway – 29th March 2016
On the 25th of March, I wrote Electrifying Didcot Parkway, after I passed through Didcot Parkway station on the way to Oxford.
Yesterday, as I passed through on the way to Bath, I took this picture of the forest of masts at the station.
A Forest Of Masts At Didcot Parkway
It does appear to me, that more have gone up over Easter, but because WordPress doesn’t let me look at galleries, I can’t be sure.
I also took this picture looking towards Oxford.
Masts Marching Towards Oxford
It would appear that the electrification is going to go at least as far as Didcot North Junction, where the West Curve from the direction of Swindon joins the Cherwell Valley Line. This schematic was clipped from Wikipedia.
Didcot To Oxford On The Cherwell Valley Line
And this is a Google Map of the same area.
Didcot To Oxford
I estimate that from Didcot North Junction to Oxford station is about ten or twelve miles.
This would mean that if an IPEMU could reach Didcot Parkway station using overhead electrification, it could undoubtedly reach Oxford and then get back to Didcot.
Between Reading and Didcot, it would appear that the wires are going up.
Wires Between Reading And Didcot
This picture shows the wires over the two slow or relief lines.
How Long Would An IPEMU Take From St. Leonard’s To St. Pancras International?
If an IPEMU is going to be used between St. Leonard’s and St. Pancras International station, there are two possibilities.
- A 110 mph IPEMU based on existing Class 387 trains.
- A 125 mph IPEMU based on a purpose-built Aventra. Ian Walmsley stated in the April 2016 Edition of Modern Railways that a 125 mph Aventra is possible.
This compares with the 143 mph and 100 mph speeds of a Class 395 train on high speed and classic lines respectively.
For this estimate, I will make the following assumptions.
- St. Leonards takes four minutes longer than Hastings.
- The baseline time from St. Pancras to Ashford is 38 minutes in a Class 395 train.
- Times on the high speed section are in proportion to the train speed.
- The baseline time from St. Leonard’s to Ashford is 46 minutes in a Class 171 train.
- All trains on the unelectrified section are limited to 100 mph.
Times From St.Leonards to Ashford
The Class 171 train takes 46 minutes, but it is only a benchmark, as few would go to Ashford and then get on a Class 395 train on High Speed 1.
The Class 395 train and the IPEMUs would be quicker as they would save a couple of minutes at each of the typical five stops, because of their faster acceleration.
Two minutes a stop would save ten minutes.
Times From Ashford to St. Pancras
Doing a simple calculation based on train speed gives the following times.
- Class 395 train – 38 minutes
- Class 387 IPEMU – 48 minutes
- Aventra IPEMU – 43 minutes.
Times from St. Leonards to St. Pancras
Adding the two times together gives.
- Class 395 train – 74 minutes
- Class 387 IPEMU – 84 minutes
- Aventra IPEMU – 79 minutes.
With Hastings it will be four minutes less.
In Wikipedia, there is a section called Future for the entry for the Marshlink Line. This is said.
The line is strategically important, as electrification and junction improvements would mean that High Speed 1 trains could travel directly from St Pancras International to Hastings. Amber Rudd, Member of Parliament for Hastings, has campaigned for electrification works to start by 2017. The aim is to reduce times to London from Hastings to 68 minutes, and from Rye to under an hour. This would require remodelling Ashford International station so the existing Marshlink line could connect to HS1, installing power systems, and adding a passing loop at Rye, all in addition to requiring new trains.
I think that the aim of 68 minutes from London to Hastings is a modest one, but as my crude estimate was only six minutes longer, I think the 68 minutes is totally attainable, especially as my times from St. Leonards to Ashford are just based on current timings and taking off a couple of minutes for each stop.
But if the Marshlink Line could be significantly improved, then time reductions of several minutes could well be achieved.
Electrification Of Bath Spa Station
Bath Spa Station could present a unique mix of electrification problems.
- It is a Grade II* Listed Building.
- It is situated in a World Heritage Site.
- The station sits on a viaduct between the River Avon and the City.
- Traditional electrification of the Great Western Main Line Through Bath, would be a challenge to the best engineers.
- Electrification will present aesthetic problems.
This Google Map shows the cramped location.
Bath Spa Station
At least it is close to the bus station, which can’t be said for that many stations.
As with Electrifying The Great Western Through Sydney Gardens, the engineers are thanking Brunel.
Look at this picture of the lines through the station.
Lines Through Bath Spa Station
Engineers must surely be able to use some system to erect the wires on this wide viaduct, that was designed for Brunel’s broad gauge.
- A solution similar to that used in Paddington station could be used in the station.
- Central masts could be erected, with the overhead wires on either side.
No wonder that the Great Western Electrification is running so late, if every station is as difficult as this one.
These are a few pictures of Bath Spa station.
I’ll be looking forward to comparing them with pictures taken in a year or two, after the wires are in place.
Electrifying The Great Western Through Sydney Gardens In Bath Spa
The Great Western Railway runs i through Sydney Gardens in Bath. This picture shows an InterCity 125 running through the gardens.
An InterCity 125 Passes Through Sydney Gardens
Note.
- There is plenty of width, as the line was built for broad gauge trains.
- Height might a bit tight, when you add in the pantograph.
- I would think that the structure under the track is pretty sound, as it’s had masses of pounding for years from Castles, Kings, Warships and InterCity 125s.
- I suspect that the bridges over the line have been fully surveyed and like most of Brunel’s structures are well designed.
So I suspect that the track could be arranged, so that it positioned the train in the right place, to allow a Class 800 train to pass through with absolute safety.
The tracks could be moved closer or further apart to match the geometry of the bridges.
The tracks could be lowered if required.
If necessary, as is often done in tunnels, a solid concrete slab track could be laid. But this can create more noise.
I wouldn’t be surprised to see an innovative rail system used in Sydney Gardens to make sure the trains run accurately, reduce noise and improve the look of the railway.
But then after Dawlish and some of the challenging situations, Network Rail has faced with tracks in the last few years, I suspect they’ll come up with a very acceptable solution.
The problem is the electrification.
Engineers will renew switches and crossings at Bathampton Junction, and will lower the track at Sydney Gardens, as well as at Hampton Mill and Meadow Farm bridges.
They will install specially designed electrification equipment in Sydney Gardens, which is classed as a World Heritage Site. Work on Box Tunnel will continue over the entire six-week period.
So as I thought height is tight.
This was a comment from the article.
When these plans were presented in the Guildhall last year, the Network Rail representative emphasised that the brackets hadn’t been finalised. The poor guy had the patient of a saint as he dealt with audience members insisting that trains be fitted with batteries to enable them to do without overhead lines in Bath as well as suggesting that they could coast through the city un-powered.
I don’t think it was a good meeting for Network Rail.
As an engineer, I agree with the comment about battery trains, but the Class 800 trains are not to my knowledge able to accept batteries at the present time. Although, judging by the way the industry is going, I suspect that within a few years, all electric trains will have provision for batteries, if the operator wants them.
In some ways, I feel that Brunel might be providing the solution.
To erect overhead wires for railway electrification, you need to support the wires every fifty metres or so.
This Google Map shows the gardens.
Sydney Gardens, Bath
Note there is a solid road bridge over the railway at both ends of the gardens, with Beckford Road in the North and Sydney Road in the South.
I estimate that the distance between the two road bridges is two to three hundred metres.
In the middle is the footbridge from where I took the picture of the InterCity 125 and another wider bridge.
As the trains will not be going flat out at 200 kmh through here, as they’ll probably be stopping at Bath Spa station, I suspect that the four bridges could be used as support for the overhead electrification.
This Network Rail visualisation shows the footbridge with a Class 800 train going underneath.
Sydney Gardens Bridge And A Class 800 Train
It looks to me, that the wires are attached under Brunel’s bridges and that by clever design tNetwork Rail can get an solution acceptable to all.
One of the problems, is of course making sure, that pedestrians on the bridge are safe, with 25KVAC overhead electrification underneath.
By lowering the track, they are increasing the safety distance and also making it less likely that naughty dogs can get on the track.
I have a feeling that this problem, will be one that will haunt Network Rail.
This picture was taken from the Sydney Road bridge and shows the area of the visualisation.
The Footbridge In Sydney Gardens, Bath
As the train appears to be on the left track, the visualisation actually shows the back of a train.
This is a gallery of pictures that I took in Sydney Gardens.
It would be a shame to ruin the gardens, by some less than adequate design.
Electrification At Paddington Station
I took this picture looking across the lines at Paddington station.
Electrification At Paddington
The nearest platform, which is number one, is not electrified yet. note the bar across the tracks which is used to support the wires.
This picture shows wires installed over platforms four and five.
Electrification At Paddington
Note where the support is yellow, that you can just see a slim vertical support for the overhead wire.
It certainly seems to be more of a sympathetic design than the gantries I discussed in Aesthetic Problems With Overhead Wires On The Great Western
Hanwell Station – 28th March 2016
I took these pictures as I went over the Hanwell Viaduct and Through Hanwell station.
All seems to be getting ready for electric services to start in May
Southall Station – 28th March 2016
I took these pictures today at Southall station.
It looks like as at Hayes and Harlington station, some of the catenary has been replaced or updated.
West Ealing Station – 28th March 2016
I took these pictures as I passed through West Ealing station.
The only definite conclusion I made, was that I will have to visit to be able to make any conclusions about how the Greenford Branch will be run after it loses its direct connection to Paddington.
Wikipedia says this about how Crossrail will affect services on the Branch, in a Future section.
In 2017 Crossrail is due to begin using two of the four tracks of the Great Western Main Line and the Greenford service will terminate at West Ealing, rather than continue to Paddington, to obviate interference with Crossrail, and to create track capacity for increased services to Heathrow. In compensation the branch line service will increase from two to four trains per hour.
When this will happen, I can only guess that it will be at the same time, as electric services start between Paddington to Hayes and Harlington.
At present the trip between West Ealing and Greenford takes just seven minutes, so if one train was to work the branch, there would be no problem doing the four seven minute legs required for two trips per hour, but four trips with eight legs might be a bit tighter, especially if something delayed the train like say a party of thirty schoolchildren or a group of three or four in wheelchairs with their carers wanting to go shopping.
Given too,that a good service for passengers would probably need.
- Similar frequencies of the Paddington to Hayes and Halington service and the Greenford Branch line.
- The Greenford Branch train would probably arrive at West Ealing a few minutes before a train to Paddington.
- The train from Paddington would probably arrive at West Ealing a few minutes before the Greenford train left.
In my view good connections are essential, as a lot of people will not be pleased to have lost their direct service to Paddington.
This map from carto.metro.free.fr shows the layout of the lines at West Ealing.
Lines At Wes tEaling
Note how there is a connection to the West.
This second map from carto.metro.free.fr shows the layout of the lines at Greenford.
Lines At Greenford
Given that to the West of Greenford, the lines connect to Chiltern, you just wonder if someone has a plan to improve connectivity in North West London.
But the branch does have some negative factors, that mitigate against development.
- There would appear to be no suitable Southern terminal to the West of the branch.
- Three of the stations on the branch can only handle two-car trains.
- The branch is not electrified.
- The terminus at Greenford is a bay platform, squeezed in between two Underground tracks.
A lot will depend on the trains and the operators of the Greenford Branch, as to what happens.
At present, the branch is run by GWR, but there has been talk about the branch coming under control of London Overground.
GWR would probably run the line as they do now, with a two-car diesel Class 165 train.
Would London Overground run the line with a IPEMU version of their new Class 710 train, as Aventras can be fitted with on-board energy storage?
The Steventon Bridge Problem On The Great Western Railway Electrification
Roger Ford in an article in the April 2016 Edition of Modern Railways, which is entitled GWEP Target Dates And Costs, discusses some of the problems of the electrification.
In one section he talks about the problems caused by the Grade II Listed Steventon Bridge.
This is a picture I took of the bridge from an InterCity 125
Steventon Bridge
Not the best, but it shows the design of the bridge.
This Google Map shows the Great Western Main Line, as it passes just to the south of the village of Steventon in Oxfordshire.
GWML Through Steventon
The bridge is on the Easternmost crossing of the railway, with the other two crossings being level crossings.
Roger explains the problem, which is about putting the overhead electric wires under the bridge.
The overhead wires have to be at maximum height over the level crossings and this means to get the wires under the bridge, they have to dip sharply. This means that excessive wear is caused to the contact wire.
It would appear from the article, that Network Rail are still searching for an acceptable solution.
At least it would appear that one of the level crossings is going to be closed, which could ease matters a shade.
But will the locals put up a fight as Mark Whitby has at the Ordsall Curve?
This article in the Oxford Mail is entitled Demolition of Steventon rail bridge on hold after MP intervention.
Some of the comments are priceless!
My view has a touch of the Philistine about it!
We have thousands of bridges like this and we don’t need to keep them all!
So perhaps we should save the best, but some that would cost too much to keep, should be replaced with modern bridges.
In the case of the Steventon Bridge, if the level crossings didn’t exist, it would appear that the tracks could be lowered under the bridge to give the required headroom.
As level crossings are one of the major causes of death on the railways, we shouldn’t stop until all are eliminated.
It would appear from this document, that one of the level crossings is going to be closed and a height limit of five metres placed on the other.
I think that the ultimate solution for this sort of problem will be technical.
In one of their documents about the use of batteries on trains, Network Rail or Bombardier talk about batteries being used to assist trains over deliberate gaps in overhead wires or third rail.
Third rail generally is not a problem and in the UK, it regularly changes sides and allows the momentum of the train to bridge any gap.
What is needed is a pantograph system, that can be raised to and lowered from the overhead wire with the train at full speed. I don’t know whether this is possible, but I suspect that every other country in the world would just demolish the bridge. I did find some research on the subject on the RSSB web site, which states that SNCF raise pantographs at 225 mph, Deutsche Bahn at 185 mph and Eurostar at 170 mph.
So it is possible!
As a trained Control Engineer, who spent a lot of time in the 1960s simulating dynamic systems, I believe that a system could be designed to lower and raise the pantograph before and after the difficult section.
I suspect that one of the problems here, is that the Class 800 trains that will work this line, were designed in Japan. But this section in Wikipedia about level crossings in Japan, would seem to indicate that the Japanese have a serious problem with level crossings.
