I´m not really shure what you´re talking of, but I´d say "no" in general ... but
"yes" in that special case to follow. :)

[shifting vehicles vertically]

There´s a (relatively) new feature of the patch which deals exactly with that
problem. In fact it has been developed by Josef for the DB set XL which
implemented "driving on tracks" for the first time.

Only thing you´d have to do would be to include the special patch command:

-1 * 9    0D 8E 00 FF FF 02 00 00 00

before your vehicles´ definitions. This will result in shifting vehicles up two
pixels in train windows.

This is essentially an "action 0D" (set parameter value) which sets the special
variable "8E" (how many pixels to displace sprites in train windows) to "2". See
"action 07/09" and "action 0D" for details.

BTW, there´s another useful thing to do, namely to reset the ordering scheme of
vehicles which could have been possibly changed by a prior .grf file:

-1 * 6    00 00 01 00 00 1A

resets the ordering scheme for vehicles to the default (0 ... FF). This command
should be also issued before all vehicle specific actions.
