FGW (First Great Western) have lost their 'Grandfather' rights to HSTs (High Speed Train (Inter City class 43 125 units)) stopping at many Cornish stations by introducing SDO (Selective Door Operation).

I am trying to find out and be certain which stations HSTs CAN stop at with malfunctioning SDO. This cannot be very many. I have checked Wikipedia which tells you loads of information but not platform length.

Please will someone let me know. Thanks

If SDO fails then it's non-stop Pnz-Ply with a 2+8 set, and with a 2+7 I think it's Pnz, Tru, Sau, Lsk, Ply.

Forgot about Newquay! However, the other day a TM (Train Manager, or Ticket Machine, or Temple Meads (Bristol), depending on context) who wasn't SDO (Selective Door Operation) trained worked a train in Cornwall with the rear 2 coaches locked out of use, it was a 2+7 set so 5 coaches were left open, the shortest platform is Hayle on the down which holds 5 coaches. Lostwithiel on the up is the shortest but that service didn't stop there.

Lostwithiel used to hang over the LC (Level Crossing) by a mile, used to be a bit trecherous at night.

2+7 can do most stations as reguarly its only the last coach thats locked out of use.

Thank you for the information. So hopefully it will mean that some carriages will be locked out of use until Ply rather than leaving station stops out. I do hope common sense prevails.

When travelling on HST (High Speed Train (Inter City class 43 125 units))'s through lostwithiel heading east that stop. The train managers use different doors ranging from the front two coaches through to the front four coaches. Before selective door opening was introduced there was always four carriages platformed according to the train manager. Why is there not a standard stopping pattern for Lostwithiel like there is at Menheniot, St Germans and Saltash that all have short platforms as these stations are typically the front four coaches.

Lazy TM (Train Manager, or Ticket Machine, or Temple Meads (Bristol), depending on context)'s is probably the answer or TM's that now that it can hold 4 coaches instead of the 2 which they are told it can hold, I don't know how many they are told it can hold though.

Officially it's the front two coaches (G and H) as there is no door panel at the buffet end of Coach F the next panel back is the rear end of "E" which is just about off the platform, officially the "up" at Lostwithiel holds 3 coaches.

So that will be A, B and C when it gets changed round to the back on the platform.
