There is an article about the Class 172 orders in this month's Todays
Railway UK. Apparently the 9 GOB units have been ordered, by the Angel
Trains ROSCo, and apparently they are due for delivery in 2009 before the
larger batch of 2 and 3 car units for GoVia West Midlands. I assume the
significance of the Angel finance, rather than TfL purchase, is that they
can be moved on to another TOC if at some time in the future the Goblin is
electrified?

How many 150s are currently used? Does 9 two car units allow for the
possibility of running in pairs? The West Midlands 2 and 3 cars are going to
have end gangways, apparently the Overground ones won't...
