First of all: this is a great set! I very much like the Trams (partly because of their high capacity and party because I actually know some of them) even though I rarely get to use them.
Anyway, we've been playing a two player game with Georges ECS Vectors and at some point decided to have a go at the tourist trade. That went fine for a while, but in the early 70s there was suddenly no bus available that could transport tourists. The old one (Neoplan) was no longer available and the next one (O 303) not yet. I don't know if this is by design, as their time built doesn't overlap (plus there usually is a variance associated with that, isn't there?).
In addition, the 'Craighead Goods Truck' can carry Tourists (even though just he can only manage 12), which is confusing at best

I also have a question, I'm sure it's not the fault of this set as I know this from other sets but I have to ask somewhere: Why can I refit a bus from 51 tourists to 204 passengers (Mercedes-Benz O 303)? From the detailed pages of the vehicles on this set's homepage it looks like it should be 51 each. This also applies to planes (the ideal tourist transportation one would assume), where a 747 from the PlaneSet (1.5.3) can only carry a disappointing 132 tourists instead of 450 'normal' passengers. Is there a setting or something similar that adjusts the ratio or something? Any help would be greatly apperciated ^^
In any case, one again thank you for a beautiful set!
