SWT Class 73's

[Humberside]

Can the SWT Class 73's work with Desiro's and if not will the 442's going mean the 73's might go as well?

 

[TheSlash]

The engines can give emergency assistance to Desiros and tightlock coupled stuff.

If a 73s is pulling a 450/444, they must pull that train at the top speed of 5mph
