Guys, please let's not try going over the limit. The list is already comprehensive and exausting regarding all time periods and continents. If we start thinking like "please add this one because I'm from that city", then expect another 500 trams, there's no way to satisfy everyone's wishes without going too far. Heck, I'll add another 15 from Croatia alone...
And let me be blunt and possibly rude - you've had plenty of time to suggest things, no offense anyone.
I'll add the T68, no problem but please suggest only those things I've asked you - future concepts and cargo trams.
Also, no offense anyone, I can't and won't even consider suggestions without 4/5ths of all necessary stats. BTW, I've erased several my own findings from the list because of exactly this - total lack of stats.

To answer specific suggestions:
- T68 - I've researched it before and discarded it but OK, I'll do it anyway (but I'll draw it in a Manchested United livery

A321 knows what I'm talking about, hahahaha!);
- Alstom Loop Tram - missing most stats therefore no until they're found;
- Futuristic Double-deck Tram - I've discarded this one myself because of total lack of stats. I've found only the capacity of the tram and BTW this one is intended for Stockholm by year 2025 - in any case - discarded;
- Melbourne No.17 freight tram - I wasn't able to find stats and those from the V-class cannot be applied;
- Zurich cargotram - most stats missing;
- Vienna cargo tram - most stats missing;
So, as you see, most are problematic because of missing stats. I'll sound rude once again but please do your homework before suggesting. I'm already drawing these in a way "for you", don't let all this work fall on me.
Please, no offense meant...
EDIT and P.S.
Regarding cargo trams - I'm not interested in overshadowing Andy's HEQS cargo trams.
CITY CARGOES ONLY.
