Problem with callback 10 (wagon power and visual effects) ...

Cab Car data : property 19 (traction) = 0x08 [diesel]; 22 (visual effects) = 0x40 [no effects]

In TTDPatch, callback 10 is called in the depot and every time the train reverses (i.e. terminus stations, by player, end of line).

Depending, how train has been built; cab car leading or trailing and whether the cab car leads consist (visually) or not, there are either no visual effects or the ones of the trailing engine to be shown, which can be either steam or diesel smoke (depending what vehicle (in reality) is at the other end).

In OpenTTD, CB10 has the following effect :

a) cab car leads (visually) : CB10 returns 0x40 and no effects are shown and this is correct.
b) cab car trails (visually) : CB10 returns either 0x04 or 0x0A for steam but diesel smoke is shown, this is incorrect.

Note : veh property 19 is set to traction used most commonly, but visual effects are set via CB10 at all times. The reverse happens for the engine, but that works correctly.
