I don't know the loco in question, but this works for most motors/shafts:

Cut a solt in a piece of metal so that the motor shaft can be slid into the
slot; motor below the metal, worm above. Grip/support the metal over a vice
(or similar) such that the motor is **not** gripped.  Use a hammer (and
optionally a punch) to tap the motor shaft downwards, causing the worm to
slide up the shaft. Be ready to catch the motor if/when it slides free.

The method means that the chances of bending the motor shaft, or buggering
the motor bearings are much reduced.

Alternatively, as its plastic and if you plan to throw the worm away, then a
hot soldering iron will melt the worm quickly so it can be removed.
