Fair enough, capacity is probably higher priority than comfort in this situation, even if it's a 153.
To be fair I think a 153 may be more comfortable; certainly rides better than a 197!
It's a tricky one that. The 153s have much more-comfortable seats than the modern rock-hard things found in new trains, but the Cavity (197) has aircon and better legroom (the latter is still not a patch on a 175 though).
Except 003 which is currently an ETCS test unit but will eventually join the main fleet, rather than the Cambrian fleet.
Thanks for the correction. I thought the ETCS fleet was remaining as 21 units but must be only 20 if that one is not staying as ETCS.
If I recall correctly, at the time of the initial announcement it was thought that all 77 class 197s would have ETCS, but ever since an official total was announced TfW have always stated that 21 units would be ETCS fitted I think. Unless the plan has changed as a result of TfW's new intention to cut the first and last trains on the Cambrian Coast (although that doesn't seem to have any impact on the Peak Vehicle Requirement on the Cambrian ETCS network) I would be very surprised if they are actually planning to reduce the number of ETCS-fitted class 197s from 20 to 21. If 197003 does have its ETCS equipment removed, I think it is far more likely that it would be installed into 197021 or 197042 instead (making a contiguously-numbered pool of 21 ETCS-fitted units), perhaps as a proof-of-concept to see how easy it is to convert 197s to ETCS, as craigybagel has suggested:
My suspicion is that 003 was only fitted with ERTMS to enable testing on the Cambrian to take place early on. It wouldn't surprise me if the equipment is removed and installed in one of the permanent ERTMS sets. Keeping those units with consecutive unit numbers should reduce the risk of a non fitted unit accidentally ending up on the Cambrian.
It should also be a good demonstration of how easy it is to swap equipment between trains
Maybe we will see 3 cars used on the Cambrian yet then
there's a good chance ERTMS training is not going to be contained to just a select few on the Cambrian for much longer.
Have I missed something about the roll-out of ETCS on another route served by TfW? As far as I was aware, the only planned ETCS deployments making any headway were the tunnels into Heathrow (now live if I recall correctly) and the East Coast Digital Programme (a short stretch used only by Great Northern having already gone live with sections further north to follow but as an overlay with lineside signals remaining in place). Regarding the Cambrian, my understanding is that Machynlleth depot cannot accomodate 3-car units and only Machynlleth and Pwllheli drivers now sign the Cambrian. Also, I recently wrote to James Price at TfW; one of my points being a suggestion that Shrewsbury drivers should be trainned to work to Machynlleth or Aberystwyth, rather than cutting the first morning Shrewsbury to Aberystwyth working to start from Welshpool (to avoid taxing a driver to Shrewsbury) as TfW are planning to do from December. His response to this claimed that it "would be an operational challenge for those drivers to be competent on more than one system." Presumably Machynlleth drivers are competent on conventional signalling (as well as ETCS) and similarly those drivers working the Great Northern and Heathrow ETCS projects mentioned above must also be competent on both systems - or is the Cambrian the only route which is ETCS without lineside signals?
