According to FCCs in house magazine, the last of the Southern 377/2s have been returned to Southern. This is a relief for FCC as they were hiring them whilst waiting for their delayed 377/5s to be built.
The 377/5s seem far happier running on the Thameslink route than the 377/2s, possibly because they're newer they may have a later version of software which is tweaked for the peculiarities of Farringdon, etc.
