Some types of WLs40 and WLs50

Luxtorpeda

I'm afraid that both these drawings also have some issues.

WLs40/WLs50 - just 1 pixel difference with correct size (95 vs. 96 px from 4,35 m x 22,093 = 96,1), but details could be improved, wheels look octagona and look like they are "in front" (from viewer's perspective) of the locomotive's external contour.

Luxtorpeda - First of all, these probably should be on two separate sheets, since in PKP this name was also used as generic name for other streamlined motor units, but not for the original VT63's used by Austrian railways themselves. But more importantly, I believe that their shape (esp. near the engineer's cabin) is not represented correctly, not least because they are too tall (original austrian ones were 2,64 m high - that gives 58 pixels - and You have 72), buffers on Polish ones were IMHO of different shape (btw. is that thing on the right end a snow plough?) and generally the differences between original austrian and license-built polish sets were bigger than Your drawing suggests.

Improved version of WLs40.

Better, but IMHO still not quite there: for example wheels still look like if they were "outside" (in front of) the "engine floor" (not the actual name of it - that part marked by horizontal red line on most of Your drawings).

I don't think it's matching the drawing - also height-wise. Of course it can be wrong, just saying.
