Re: "Too heavy"
Reply #10 –
The weights of vehicles AND all weight limits are actually set by the pak, so all complains about that must go to the pak makers in question. And when the paks are actually fixed so that the weight limits are sensible and consistent with vehicles available it adds to the game. Having optional feature was never a bad thing 
I do not know why the simutrans standard supported the weight limits for ways in paks when it completely ignored them in-game, but that's probably the reason why these values are such mismatched - before simutrans experimental nobody ever could find out without digging through pak source files that they were not matching properly. If it weren't for simutrans experimental, then I would never know that there even were any weight limits defined in pak files in the first place.
From what I noticed the weight problem afflicts both pak128 (most notably some buses can't fit on city roads) and pak64 (some steam engines are heavier than any track allows). Didn't really use any other paks so I can't say for them.
But why is it then that these problems with weight only appear in Experimental
