Looks like we have some interest in the build. I do need a little help, I can not find the Athearn EMD 40 for sale anywhere I want to deal with. Does anyone have one that they can measure the wheelbase for me? I have lots of small drives to use.

The wheelbase on the EMD 40 is about 46mm, which is actually a bit longer than what you would see on the prototype (see above), but it's a smooth mechanism and the longer wheelbase does help with running thru turnouts, etc ...






The actual Simplex locos have a somewhat shorter wheelbase and a Tenshodo 32mm Spud or similar would very closely approximate what you see above -- wheel journals closer together than outer edges of doors (compare to first picture).

Since the frame hides the actual journals (if any!) on the drive used, you have a good bit of flexibility in choosing a substitute drive ...

(Hopefully) helpful hint: when fitting a different drive, tack some couplers into the pilot openings and rig it so the couplers are at HO height when the kit chassis sits on the selected drive.


Cheers,
Dallas

Some days you just get lucky .

I found two of these drives in my box of bargain train show drives in minutes. I know they came from HO trolleys, the bodies were sent to Louis a while back so hard for me to ID them.



The drives have open frame motors and I will need to isolate the frame for dcc. I will now have to pull out my supply of can motors to look for a fit, if not the current motors will do.

I will also try a few more samples.

Looking at the line drawing and the wheel spacing to the door, this drive might be my better option, plus it is already DCC.




Plus the drive is very small and maybe I can add a bigger weapon.

Larry, that was a Tyco shell you sent me. The drive you have there came from a Tyco Trolley.
Also, compare the drive to this Link, you will see the same type drive I used in this build. http://www.railroad-line.com/forum/topic.asp?TOPIC_ID=21836

That's a 'shell' of a weapon you got going there! I'll be watching...through heavy lenses.

Remember that artillery adds an element of class to what would otherwise be a vulgar brawl. Go for the larger weapon!

Here is a German 75mm anti tank gun sample. I am looking for a WWI gun in 1/48. That might need to be scratch built.
