A little bird whispered in my ear that 378 005 & 007 are to start
revenue service this week. It did not say which route(s).

On a very few occasions I have see the 378 units on the slow lines at
Purley.

Well they ain't going to be in revenue service down that way, that's
for sure!

Posts in another forum seems to suggest they'll be used on the North
London Line and/or West London Line routes (some NLL services run
through onto the WLL and v.v.).

If it is this week it's just that little bit too late for the hot
weather!

(Incidentally I note that the current May-September London Overground
timetable booklet features a 378 on the front cover picture I think
for the first time, alongside the roof of Stratford station, the
Hackney Empire and the Camden Market.)
