All units have their good and bad moments but the 175s seemed to be more susceptible to it. That said, it might be because we spent so much time on them compared to the rest of the fleet it was easier to notice differences like that.
158s can be temperamental all year long - amount other issues they have a strange tendency for the power selected by the driver to not necessary reflect what the engine delivers - but thankfully I never signed Tallerdig so that was one issue I haven't had to deal with!
Oh interesting! That’s very possible.
We only sign 158’s so nothing to compare too sadly, I do wish i’d gotten to drive a 175 and not just the sim! Perhaps I’ll have to go to GWR land if they do end up down there haha!
I notice even with very few driving hours done, power selected vs power delivered varies quite a bit unit to unit.
Talerddig certainly presents some challenges, summer you can struggle with overheating, autumn not only is it very steep but it’s well known for low adhesion due to all the foliage about.
Further to that, if you travelling up Tallerddig bank (to Shrewsbury) there’s a block marker about 3/4 of the way up and if that’s closed and you have to stop there when it’s slippy, it’s incredibly difficult to get going again.
Line speed is 95 KMH (about 60mph) and even in notch 7 you will see the that the speed is still coming off ever so slightly (which I suspect is part of the reason they may overheat during summer, having to be flat out on power going up).
I’ve seen the 97’s also overheat and get stuck going up there pulling the logs.
I’m told the 197’s absolutely fly up there and your shutting off power so may very well see the end of the problem for passenger trains.
