GWR HSTs have had poorer reliability figures than the other HST fleets for years. but then they have been worked in different ways from other TOCs for years as well - and GWR had all the power cars with GEC traction motors, which were never as reliable as the Brush design fitted to most of the fleet.
Where are the operational equivalents on East Coast, the MML or XC of the Cotswold Line or the Cornish main line? Where station stops are close together, with the power cars going through repeated cycles of powering up, shutting off, powering up, etc, every 10 minutes or so - or less. There are plenty of taxing climbs in the GW area as well, be it the Devon Banks, Malvern Hills or the climb from Stroud up Sapperton bank.
All these dish out extra punishment to traction equipment, compared with running long distances at speed, which is largely how HSTs have been used elsewhere - and is what the train was originally designed to do.
Hopefully the ScotRail sets will find the Highland climbs less punishing when moving rather fewer coaches up them than sets with GWR have had to do on the steeper hills in Devon.
The Sunday MML timetable has the HSTs stopping at all stops north of Bedford towards Derby and Nottingham.
