From what I can see service on the Severn Beach Line is rather poor considering it as an urban line. Trainr every 30 minutes in each direction and run on diesel. Is there any way to improve the line perhaps converting it into a tram train, double tracking of the line and run a service every 15 minutes. I'd really love to hear local imput.
As a regular commuter on the line, an aboslute NO to tram-trains. A separate tram line up Whiteladies road and Gloucester road directly into the city centre would be far better service than buggering about with the existing lines.
In an ideal world, full double tracking and electrification would happen. However short-term what would really help is:
1. All trains 3-Car or 4-Cars. (Recognising the stock shortage problems)
2. Sort out the signal check at Narroways Hill Jn every time. I can see on Signalmaps.com there's regularly no train coming across.
Medium-term
1. Using electrification/BEMU units to extend to all trains 4-car
2. Extend Clifton Down loop to Redland - FOBSR already advocate this.
3. Extend Avonmouth loop to Portway P&R.
As part of a wider Bristol Metro plan, also I would advocate standardising the origin/destination pairs of the Severn Beach and Weston lines, as well as standardising the arrival and departure times and platforms at Bristol TM. A long-term option could also be to use the Up Through to allow 5 and 6 to function as a Penryn-type overtaking loop.
The line needs electrifying. The existing trains are slow and noisy.
Agree, although the tunnels in close proximity to stations may be awkward.
If someone in the know could share what the capacity situation on the four-track section into Bristol is, that would be interesting.
Messy, I think. Bristol TM east throat is a particular problem with conflicting moves. I think line capacity isn't too bad (1tph Filton, 2tph Bristol-Cardiff on the Reliefs on top of the severn beach services, with some other extras that would normally be on the mains but aren't for one reason or another).
Presumably we would also need additional loops on the Severn Beach line to increase service levels
It's pretty tight as it is - you can see when there are delays how quickly it propagates along the single line sections.
