Read on WNXX▸ that has been confirmed that FGW▸ will be keeping 153325 & 153333 in addition to the class 150's from London Midland.
And another forum, I won't quote it, is saying something a little different.
Unfortunately there are far too many armchair enthusiasts trying to work out what is going on with respect to the ownership of stock and the transfers that may or may not happen due to the introduction of Class 172s by London Midland. We don't always know where posters get their information, who they work for or whether they are merely repeating information that they have got from other rail forums. How do we differentiate between the information they give us and the information that posters who are "in the know" give us?
There is almost as much speculation and conflicting information about the Class 180s that may or may not be returning to FGW. Every time a Class 142 returns north for maintenance or a repaint someone somewhere, usually in the north, speculates that they're starting to go back to Northern for good. Until it returns south the following weekend of course!
Personally I think that the poster on the WNXX forum may well be correct as the Class 150s would be in service by now if they were staying just for the summer. If units come then surely borrowed units will go. If FGW do keep the two Class 150s mentioned then perhaps they won't be hiring the two units from
ATW▸ each day? What should be more of interest to this forum is the total amount of units available to FGW on a daily basis after all the stock changes have taken place.
