A DynoCar would have a generator driven from the vehicle wheels,
and a variable load so that the pulling loco's motive force can be measured.

I think what Bob was describing is simply a trailing vehicle,
holding an ammeter wired in series with one motor lead.

If your meter really does measure Amps then no shunt is required.

Take care though,
many meters with Amp scales are actually milliamp meters with a shunt,
you need to make sure the shunt is still there.
