Multi-units of dissimilar locos?

Question

I have actually spotted a multi-unit of a WAG-7 and a WAG-5 hauling an empty rake at SC. Can multi-units of dissimilar locomotives (diesel) be built? Say can there be a WDM-3A and a WDG-3A? Or a WDM-2A with a WDM-3D?

Answer 1

These days most locomotives are designed to be worked in multiple and any two or more can work in mulitiple provided they have compatible braking and control systems.

The locos will have a code or symbol on them to identify their multi-unit working capability so if you see two locos with the same code or symbol they can work together even if they belong to different classes.

If you contact the railroad operating company they will probably be happy to send you details of locos and multi-unit working. Or failing that talk to one of their staff.
