Going to be strange doing a Kingston Rounder (W-M) on a 450.Tomorrow.
Might be worth noting dwells en route. It starts to become critical that way round (in pre pandemic timetable performance parlance) from RP inwards. 450's couldn't quite match 4-458 over GF-AS (between Aldershot and Wanborough) which wasn't good in that instance due to min 5 min turnrounds at GF !
As for inner sub use of 450's it would seem that there is no option (stock wise) at present, from what I hear. Without wishing to cause any offence what so ever, a lot can depend on the crew being on the ball and up for the challenge, so to speak. I know from experience the peaks could be another matter altogether.
Many, many years ago now, 1990s if not before, I seem to recall, there were some complaints from some on the crew side (it may just have been one person, I don't know?) about the timetabling of GF New Line services, in respect of ability to keep time - it may have been during the winter season? - but suffice to say, with an experienced crew, who were keen to do their bit so to speak, these complaints were found to be groundless in principle.
Yes, no two journey's are ever the same, and yes, newbie's to the job will inevitably be more cautious in their approach to braking etc. but there has to be a point, a line in the sand as it were, when a stand has to be made in relation to the 'fitness for purpose' of the timetable.
Sorry, getting OT again!
