I was thinking earlier considering they were both built by Siemens within a few years of each other (in the 350/1's case), were the 350's built with a 360 working capability in mind? Are there any issues such as software which would prevent it from happening? And also I realise they both have Dellner couplings but are they different heights? The reason I ask this is because earlier I was thinking about how hardly any operators have uniform fleets. In my head I was plotting a small cascade resulting in the 360's being split in to two fleets, with 7 going to LM to displace the 321's to NXEA, and the other 14 going to FCC to displace the other 13 321's to NXEA. LM and NXEA get uniform fleets and FCC get some newer trains. Don't ask why I was thinking about this, I was just having a random think about how things could be improved.

But does anybody agree with me on how its bad that operators have non-standard microfleets when with a bit of cascading quite a few of these could be ridden of? It seems like bad planning on the DfT's part for leaving small fleets at TOC's such as the 7 321's at LM.
Does anyone know what’s happened to the European new rolling stock notice put out by London Midland? Either last year or the year before? Because...
What id go for would be something on the lines of:
London Midland orders a new batch of either 350s or Desiro City units, This then displaces the 323s to Northern Rail, and possibly even displaces the 321s if thurther 350s are constructed...
Northern Rail then gains the complete 323 fleet; this is then further met by...
Thameslink Arriving and...
First Great Western gains East Anglia’s 360 Fleet - displaced by the 7 LM 321s and 321s or 317s from FCC...This being met by the former Heathrow Connect 360s - Giving First Great Western a more uniform fleet ot 26 Desiros for Thames valley services...
Would any of that work? FGW currently has 21 166s & 36 165s - While this would relive the 166 fleet, it also solves the problem of what to do with 5 360s displaced by Heathrow Connect / Crossrail...
And another suggestion for the displacement of 165s would be to electrify the Greenford branch, and merge it into Crossrail, possibly as a branch run from Crossrail's Paddington station - possibly extending the electrification thurther up towards Ruislip?
Just trying to work out a way which various units can be cascaded around the country - mostly by reducing the micro fleets we currently have - And Although it would mean Northern Rail wouldn't be receiving any newer stock for a while, it would certainly give the Northern Franchise a fair shove up on Electrified units and capacity - More uniformed fleet of 323s - which can displace the pacer fleets running on electrified lines, and with thurther electrification, more 319s displaced from Thameslink & the GWML...
