Thoughts On Lumo’s Proposed Paddington And Paignton Service
Modern Railways says this about Lumo’s proposed new service between Paddington and Paignton.
Under the plans for Paignton, announced on 5 December, there would be five return Lumo trains running between Paddington and Paignton, serving Bath Spa, Bristol Temple Meads, Taunton, Exeter St David’s and Torquay. These could start in May 2028. A sixth path is planned between Highbridge & Burnham and London Paddington.
Modern Railways says that currently there are only three direct trains between Torbay and London and that rail has a 29% modal share on that route compared to 71% for road.
Modern Railways tell us that GWR current run three trains per day to Paignton and these call at Reading, Newbury, Hungerford, Pewsey, Westbury, Castle Cary, Taunton, Tiverton Parkway and Exeter St. David’s and Torquay.
Note.
- Lumo will be taking five stops using a longer route.
- GWR currently take ten stops using a shorter route via Westbury.
- GWR currently take ten stops between London Paddington and Bristol Temple Meads.
- The fastest GWR service I can find takes three hours and four minutes between London Paddington and Paignton.
- The fastest GWR service I can find takes one hour and thirty-five minutes between London Paddington and Bristol Temple Meads.
- The fastest service I can find takes one hour and thirty-nine minutes with five stops between Bristol Temple Meads and Paignton.
- Lumo’s trains will probably be fitted with traction batteries rather than diesel engines, so it is likely, that the fewer stops they execute will be done quieter and faster.
I would not be at all surprised to find that Lumo’s journey times would be of this order.
- London Paddington and Bath Spa – One hour
- London Paddington and Bristol Temple Meads – One hour and thirty minutes
- London Paddington and Taunton – Two hours
- London Paddington and Exeter St. David’s – Two hours and thirty minutes
- London Paddington and Torquay – Two hours and fifty minutes
- Paddington and Paignton – Three hours
These sections would not be electrified.
- Chippenham and Bristol Temple Meads – 24.4 miles
- Bristol Temple Meads and Paignton – 103.8 miles
In Fast Battery-Electric Hitachi Trains Between Paddington And Bristol Temple Mead Stations, I discuss how Lumo and Great Western Railway will speed trains to Bristol Temple Meads via Bath Spa and Chippenham.
If 128.2 miles on batteries sounds a tough ask, remember that a similar-sized Stadler Addu ran 139 miles on one charge in 2021. Lumo, Hitachi and their battery makers from Sunderland didn’t enter this contest to come a distant second.
Paignton has a big advantage, as this OpenRailwayMap shows.
Note.
- Paignton station is marked by the blue arrow and writing at the top of the map.
- There are two platforms, one of which normally handles arrivals and the other departures.
- There are the Goodrington Carriage sidings to the South of the station.
I’m sure Hitachi will electrify some of the sidings, so that Lumo’s trains can leave Paignton with full batteries. But they only need enough charge to cover the 128.2 miles to Chippenham!
I have a few extra thoughts.
The Train’s Batteries Will Get Bigger
Hitachi must have access to the best battery chemistry, that the world and especially Japan can offer.
I feel very strongly, that the performance of Hitachi’s trains will get better, as the years progress.
Pairs Of Trains Could Be Used
I suspect all the stations that will be used by the service ; Paddington, Bath Spa, Bristol Temple Meads, Taunton, Exeter St David’s, Torquay and Paignton can handle a pair of five-car Hitachi trains on a busy day.
The Goodrington Carriage sidings at Paignton station would certainly appear to be long enough.
This could be useful.
An Early Bath
Consider.
- Currently, the fastest trains to Bath Spa take one hour and fourteen minutes from London Paddington.
- But the trains do make as many as three stops at Reading, Swindon and Chippenham, before they stop at Bath Spa.
- London Paddington and Bath Spa are 106.8 miles apart.
- The route is fully electrified between London Paddington and Chippenham.
This is an average speed of 86.6 mph.
Lumo will have two advantages
- They will be making Bath Spa the first stop.
- They will be able to maintain at least 100 mph for a large part of the route between London Paddington and Bath Spa, by the use of traction batteries, where there are no wires.
- To go between London Paddington and Bath Spa in an hour, requires an average speed of 106.8 mph
If they could average 100 mph, the time would be 66 minutes.
Bath Spa may not be an hour from Paddington, but it will be very close to it.
I would expect that a fast service to Bath could fill up with day-trippers.
How Long Will A Round Trip Take?
If I’m right that Lumo’s battery-electric high speed trains will be able to do one-way in three hours, then adding in half-an-hour to turn and charge the train at Paignton would suggest a six-an-a-half hour round trip.
How Many Trains Will Be Needed For A Full Service?
Lumo are talking of five round trips per day to Paignton and one to Highbridge & Burnham, so this would probably need two trains to run the service.
The Wikipedia entry for Highbridge & Burnham station says this.
A loop on the west side of the line south of the station can be used by goods trains in either direction, southbound trains crossing over to run wrong line through the northbound No.2 platform to do so. This crossing also allows terminating passenger trains from the north to reverse here if required.
Perhaps this loop will be used to allow one train to start from here in the morning and at the end of the day stable here overnight.
The loop could be electrified to make sure that the first train of the day gets to Chippenham.
Trains could follow a schedule like this.
- Train 1 – Leaves Highbridge & Burnham – 06:00
- Train 1 – Arrives London Paddington – 08:00
- Train 1 – Leaves London Paddington – 08:30
- Train 1 – Arrives Paignton – 11:30
- Train 1 – Leaves Paignton – 12:00
- Train 1 – Arrives London Paddington – 15:00
- Train 1 – Leaves London Paddington – 15:30
- Train 1 – Arrives Paignton – 18:30
- Train 1 – Leaves Paignton – 19:00
- Train 1 – Arrives London Paddington – 22:00
- Train 2 – Leaves London Paddington – 06:30
- Train 2 – Arrives Paignton – 09:30
- Train 2 – Leaves Paignton – 10:00
- Train 2 – Arrives London Paddington – 13:00
- Train 2 – Leaves London Paddington – 13:30
- Train 2 – Arrives Paignton – 16:30
- Train 2 – Leaves Paignton – 17:00
- Train 2 – Arrives London Paddington – 20:00
- Train 2 – Leaves London Paddington – 20:30
- Train 2 – Arrives Highbridge & Burnham – 22:30
Someone with more experience of writing timetables could make this work.
But it does appear to me, that using Highbridge & Burnham station for an early start and an overnight charge of one of the trains could mae the whole service work.
