The Anonymous Widower

Bath Spa Station – 28th July 2020

I took these pictures as I twice passed through Bath Spa station.

These are my thoughts.

Electrification Gantries On The Platforms

As somebody, whose eyesight is on the wane, I am not a lover of electrification, where the gantries are bolted to the platforms. These pictures show some installations of this type at Crouch Hill station.

Would electrification gantries like these, be appropriate in Bath Spa station?

Could Lightweight Electrification Gantries Be Placed Between The Tracks?

These pictures show the wide gap between the two tracks in Bath Spa station.

Could double-track lightweight structures, based on a design like this be placed between the tracks?

These structures are made out of laminated wood and are surely a possibility.

A Makeover For Bath Spa Station

If you look at much of the woodwork and paint in the fabric of the station, it appears tired and in need of refurbishment.

Whether the station is electrified or not, the station will need a high-class makeover.

Services Through Bath Spa Station

Three train companies run services through Bath Spa station.

There are also some freight services hauled by diesel locomotives.

Trains leave Bath Spa station using one of three routes via either.

Most trains seem to go via Bristol Temple Meads station.

  • The distance between Bristol Temple Meads and Chippenham stations are 24.5 miles.
  • The distance between Bristol Temple Meads and Westbury stations are 28.5 miles.

Neither distance is that long.

An Alternative To Full Electrification

When I look at the distances between Bristol Temple Meads, Chippenham and Westbury stations, they tell me that they are within the range of Hitachi’s Class 800 train with a battery electric capability or Regional Battery Train, which is described in this infographic from the company.

The proposed 90 km or 56 mile range would even be sufficient take a train between Chippenham and Bristol Temple Meads stations on a return trip.

Notes for each station follow.

Bristol Temple Meads

Charging facilities would be needed.

Destinations in battery range would include.

  • Bristol Parkway – 6 miles
  • Cardiff Central – 5 miles to the electrified Great Western Main Line.
  • Cheltenham Spa – 41 miles
  • Gloucester – 39 miles
  • Taunton – 45 miles
  • Weston-super-Mare – 19 miles

Note.

  1. Return trips to Bristol Parkway and Western-super-Mare would be possible.
  2. The other destinations will need charging facilities.

Bristol Temple Meads station could become a major hub for battery trains.

All local services and all passing longer distance services could be trains with a battery capability.

I write more about Britol Temnple Meads station as a battery train hub in Bristol Temple Meads Station – 28th July 2020.

Chippenham

A train would leave Chippenham station with a full battery after charging on the fully-electrified route from London.

Chippenham and Weston-super-Mare would be in battery range with a charging facility at Weston-super-Mare station.

It should be noted that every extra mile of electrification past Chippenham, can be added to the distance electric trains with a battery capability can reach.

Westbury

Charging facilities would be needed.

Destinations in battery range would include.

  • Salisbury – 24 miles.
  • Southampton – 49 miles to the electrified South Western Main Line, at Southampton Central station.
  • Weymouth – 53 miles to the electrified South Western Main Line at Dorchester Junction.

Note.

  1. A return trip to Salisbury would be possible.
  2. Trains would need to have the capability to access 750 VDC third-rail electrification.
  3. A few extra miles of electrification may make operation South from Westbury station easier, more reliable and allow more destinations to be included.

Westbury station could be a major hub for battery trains.

This Google Map shows Westbury station and the lines around it.

I would probably electrify a few miles either side of Westbury, so that passing trains could be in contact with the overhead wires for perhaps five to ten minutes and take a good long drink.

  • Electrification could be either 25 KVAC overhead or 750 VDC overhead.
  • Newbury, where the electrification to London starts is 42 miles away and trains can pick it up at speed.
  • Taunton is 47 miles away and could be electrified to Exeter St. Davids.

Great Western Railway could run all their services between London Paddington and the South-West using Class 800 trains with a battery capability.

Conclusion

The prolitical, heritage and engineering problems of electrifying through Bath Spa station can be voided, by electrification and charging facilities at stations like Bristol Temple Meads, Taunton, Westbury and Weston-super-Mare.

Reinstatement Of Rail Access To Devizes Via A New Station At Lydeway

This is one of the successful bids in the First Round of the Restoring Your Railway Fund.

Devizes is a growing town without a railway station.

The Wikipedia entry for the former Devizes station, says this about providing a new station.

Although Devizes was denied a railway station due to its stagnant population, as of 2017 the population had grown to 31,000, which could warrant its re-establishment. However, much of the vital land agreements and rights of way were sold off reducing the chances of reinstatement. An alternative plan has been proposed: to build Devizes Parkway Station at Clock Inn Park, three miles east of Devizes on the Reading–Taunton line, near to the site of the original junction for the branch at Etchilhampton.

It appears to have been taken from Baldrick’s book of cunning plans, where you create a virtual branch line using the A342, travellers’ personal transport and a shuttle bus service.

This Google Map shows the position of the station site at Clock Inn Park, with relation to Devizes.

Note.

  1. Devizes in the North-West corner of the map.
  2. Clock Inn Park in the South-East corner of the map.
  3. The A342 road connecting the town with the station site.

This more detailed Google Map shows the station site.

Note.

  1. The A342 going diagonally across the map.
  2. The Reading-Taunton Line going across the map.
  3. There’s even bus stops by the station site.

As the site could be fairly generous, I think a station with adequate parking could be created.

The Train Service

The train service is currently two hourly on this route between Paddington and Exeter St. David’s stations.

Perhaps, with an extra stop and more passengers, the service could be increased to hourly.

Another alternative would be to run battery-electric trains on the route between Paddington and Westbury, that called at all stations West of Newbury.

  • Trains would use the electrification between Paddington and Newbury and would leave Newbury with a full battery.
  • This service would be an extension of the current hourly service to Bedwyn station.
  • Between Newbury and Westbury stations is forty-two miles of unelectrified lines, which should be possible with a battery electric version of the Class 802 train.
  • Charging facilities would be needed at Westbury station.
  • Between Paddington and Westbury stations takes one hour and thirteen minutes.
  • Hitachi are quoting a ten minute charge time for one of their battery-electric trains.
  • The trains would turn at Westbury station, which has refreshments and toilets for the crew.
  • No extra electrification would be needed to run electric services to Westbury.

I think it could be feasible.

The Concept Of An Electrification Island

Westbury could be what I would call an electrification island.

Consider

  • The Reading-Taunton Line passes through the station.
  • The Wessex Main Line both passes through the station.
  • The town of Westbury has a population of around 17,000 and some substantial heavy industries, so I suspect that it has a robust electricity supply.
  • Taunton is 47 miles away.
  • Newbury is 42 miles away.
  • Weymouth is 59 miles away.
  • Bristol Temple Meads is 40 miles away.
  • Swindon is 32 miles away.
  • Hitachi are claiming a range of between 55 and 65 miles for a battery-electric train.

Suppose the two routes through the station  and perhaps for up to ten miles away from the town, were to be electrified.

  • A battery-electric train turning back at Westbury would pan-up in the station and charge the battery. Leaving the station, the driver would leave the pantograph up for acceleration and then make sure pan-down was performed before the end of the electrification.
  • A through battery-electric express between Paddington and Exeter would pan-up when under the electrification and pan down before it left the electrification.
  • It might be prudent that all passing expresses stopped in Westbury station, to make sure, trains didn’t stop with a flat battery in the middle of nowhere, until procedures were seen to be totally reliable.
  • A battery-electric train to and from Weymouth would probably need to run for about 45 miles between the electrification island at Westbury and the third-rail electrification at Dorchester Junction.

I believe that a well-designed electrification island at Westbury coupled with perhaps electrification between Exeter and Taunton, would enable battery-electric trains to work the following routes.

  • Paddington and Exeter
  • Westbury and Bristol
  • Westbury and Weymouth
  • Westbury and Swubdon

I suspect that Transwilts services could also be run by battery-electric trains, as they could charge at Westbury, Swindon and other electrified stations.

Conclusion

Devizes Parkway station would appear to be a simple way to provide a new station, at a town that has grown substantially since the days of Dr. Beeching.

Did Dr. Beeching and the Government of the day, have a view on population growth in the UK? They certainly didn’t take it into the account in their rail closure program. Or if they did, they got it spectacularly wrong!
