There were several different threads I could have posted this on but as it covered multiple different stock types it seemed best to create a new thread. Here is the news story from TRansport Scotland http://www.transportscotland.gov.uk...in-improvement-programme#sthash.rxGX7JS8.dpuf A couple of new bits of information here as well as retreading some old ground. 321s now coming in early 2016 rather than December 2015. AT200s starting operation in Autumn 2017 Updated timescales for the 318 refurbishment Interesting information about the power socket installations being separate from the refurbishment programme. This makes sense as there is a commitment to install sockets on all other train classes including the "refreshed" 156s and the 170s that are not receiving a refurbishment. Not sure if this will be done in house or through a separate contract once they have a bit more spare stock to enable more withdrawals.
