Additionally, someone in the know might want to update the TTDPatch wiki to say exactly when each vehicle property is updated by callback 36. At the moment it just says "most" do this, while "some" do that; very vague indeed.

Seems to me there is no other solution to this problem than to invalidate the complete vehicle cache. We might "optimise" this a bit by only running this once per tick if it's needed, but that only really matters when crossing a different type of track with a relatively long train.

A (semi) optimisation could be to only look at the from engine for the rail type, but that is probably bound to cause more trouble than it's worth.

NOTE: also update the track conversion method as the UpdatePower thingy has the same issue there. It should probably update it if it's not powered as a NewGRF can use the railtype regardless of its poweredness.
