I think from your original question do you mean the difference between a tram loco (for example the Fiery Elias) and a self contained tram?I was talking of differences from garden railway perspective and not from real world view
But I bet someone somewhere has a pic which shows differentl!!
Some interrurbans ran up to 4-car units - the Pacific Electric
AH Brilliant I was not getting too far-fetched then fitting single arm Pantograph to one of mine!!Happy to oblige..............!!
The Adelaide-Glenelg ones ran as coupled pairs in peak hours (here in 2004)

and US interurbans (admittedly a bit more "heavy rail" than our concept of tramways) ran in multiple , like this preserved North Shore Line pair at Union, IL

I don't think there is a definitive test to determine the difference as far as the vehicle itself is cocerned - but my understanding has always been that - because of the increased danger associated with running in close proximity to humans and small animals - the main feature of a tram as distinct from a locomotive is the extra eclosure of the running gear which can amount to all round skirting.
