Probably due to todays unit shortage. The SWT hire in did not operate on its booked diagram if at all! 158955 (2 car) operated in its place. I have also noticed that 158751 has been made as 2 car from 158950. There seems to be a lot of messing about when it comes to 158s at the moment.
Stock variations on that particular service are quite commonplace, sometimes a 150 will turn up. Pot luck! :roll:
There have been various rumours about more three cars, I heard one a while ago that they were all going back to two car to be run in pairs, etc etc... But in reality I don't think there are any anticipated changes soon, just the everyday business of reshuffling them due to maintenance requirements etc.
The Great Malvern - Brighton working is usually a 2 car 158, on weekdays anyway.
Someone correct me if I'm wrong, but I'm pretty sure the idea that Pacer's can not run on lines with third rail present is a myth, as they run over them on a daily basis in the North somewhere where it adjoins Merseyrail, although the location escapes me.The closest I've had out of Trowbridge is a 143 on the morning Bristol - Pompey about 3-4 years ago, and had Swansea on the front! It was of course duly swapped for a 158 at Westbury as 143s cannot enter 3rd rail land, though the dispensation was temporarily lifted when they went to Eastleigh works


Pacers are definitely banned from the Southern. There refurbishment at Eastleigh and moves there were a one off. The issue with 153s is steps I believe, I don't know if they were fitted when converted to 153s from 155s but they are the problem now. The last time a 153 made it to Portsmouth I believe the steps had to be removed before it returned.
As for the Pacers, I think it's a pretty safe bet that if they were permitted to operate down to Portsmouth, it would have happened by now, with all the disruption on Portsmouth - Cardiff in past years.
I know pacers dont go past Warminster because the crew that join the train at Westbury to Portsmouth dont sign pacers! Its not a case of them being banned. The Warminster terminating service is operated by Bristol/Gloucester crew.
