SR is down to 6 x 156s in Barbie livery - 156450/453/465/474/476/493; and a dwindling number of 314s remain in Strathclyde livery.
Tony Booth has been a great compiler - is there more to this than just the email - is Tony okay? Very unlike him to stop his site without notification, and over 3 months would appear to be more than an email problem.
According to scot-rail.co.uk, 156474 has been refurbished and 156450 is at Springburn.
Fully agree on the latter, hopefully Tony is okay.
