The Aristocraft Class 66 was a brave attempt to woo an international customer base - a valid one, as it happened, as the locomotives, built at the GM plant in London Ontario, were sold all over Western Europe. They were, after all, little more than a loading gauge adjusted AC4000 - the 4000 being the horse-power.

They were, even allowing for the rather odd scale, a very fine model indeed, and shared all their running gear with Aristocraft's immensely powerful Dash-9 model, one of which hauled 100 cars around the promenade deck of the old Cunarder, the 'Queen Mary', located in Huntingdon Beach CA.

I don't think I'll be able to compete with the power of the Aristocraft. I'm currently looking at a motor on each axle to make the suspension easier, but even cumulatively my little motors might be a bit too small. If it's too feeble I will look at using two 540 size motors on the chassis with drive shafts to each bogie, and the current design may end up on an EMU, where I can power every axle and not worry about pulling anything else.
 
I would suggest you have a look at an LGB / piko / aristocraft gearboxes to get an idea of how they are laid out, there's no point reinventing the wheel here. One motor per bogie would be enough here. You may need to add weight later for traction as required.

here is a list of some of the buhler motors used by lgb

You may also want to incorporate space for a reed contact board such as

in your gearbox design - this would allow a sound chip installed in a locomotive to activate up to to sounds (typically whistles) at particular positions in the track

Thread 'Scratch built 66 project'

Here's a bit of progress on the 66 idea I introduced in my introduction.
As a starting point I have used the gears suggested in "3D printable traction motor case", posted here by @Melbournesparks. I had a problem with the 2mm bearings. After 'coaxing' them onto my axles they are no longer bearings, but the duplex gear is free running anyway so I will just print some solid bearings.

This design is running a bit fast for these tiny brushed motor and wheel diameter. (driven at 7.4V) So I'm going to have to change things around a bit.
The weight of the chassis is going to be taken by...
