Two reasons I'm interested if your report of 345025 is correct
* one is that I haven't seen it reported in service yet, but clearly it could be - it certainly does appear to have been tested west side
* there is a unit berthed at Plumstead with the headcode 5Y25 (along with 5Y49, 5Y50 and 5Y53) and has been since 20 April. The use of 5Yxx or 9Yxx headcodes has previously been a good indication that the unit is 3450xx, although I could have been reading too much into that.
