I have updated the part names based on this information - to remove the
voltage designation and correct the dimensions.

I'm confused. Are these parts generally openable - are the actual motors
removeable (by the average user)?  If they are removeable, then the
(shortcut) names should include "case", since they aren't actually the motor.

If the motors are not removable, then the c01 files should be "Complete", not
"Shortcut", and the voltage designation should remain.


Yes, including case is good.

As Niels indicated, the 4 x 12 x 3 1/3 versions are openable with a screwdriver,
allowing the actual motors to be replaced, so I think the term "Shortcut" is
correct.

The 4 x 12 x 4 version is glued, so I'll change that to "Complete".

I think I might also generate two small red/white sub-pseudoparts for the
voltage indication, and include these in the shortcuts to show through the
hole.

If you're going to do that, you might as well put the voltage in the part names
(for the shortcut/complete files).

Of course - that was my plan. The voltage valiue that is visible through the
"window" is part of a sticker on the actual motor, but I don't think we need to
model all the guts.


That way we can have voltage-specific shortcuts (which should help peeron and
bricklink straighten out thier inventories), without needing to make the
casing voltage-specific.

(showing my lack of knowledge on pre-9V trains) Was the casing used for multiple
voltages?  This thread has only mentioned 4.5V.


That's what Niels confirmed - I had to <SNIP> his response due the LUGNET 90%
comments blocker.

(...) The actual motors (both 12V and 4.5V) were sold seperately as replacement packs, so users can screw open the case and replace the motor (either replacing a broken motor or replace a 4.5V motor with a 12V motor or vice versa).
