[Class 37 or Class 55? Bachmann Bogies]

Fantastic,

 

I have a couple of poorly Bachman 37’s and with the growing number of cheap 55’s on ebay I was considering one for spares.

 

Despite the wheel dimensions, do you know if the gearing / axle is the same on 37/55 models ? (Ive a split gear and was considering to swap a wheel, but after reading that maybe an axle swap is what i need ?).

 

the actual bogie side frames themselves should be different, not just the steps, but 55 bogies were cast not fabricated and look different.

 

Here's the 37, note the "rim" outline all round the top section of the bogie, there is no indented/ depressed section on the 55 or the 50 bogies.

 

seen clearer on the Hornby Class 50...

[Micro layout-£50 budget?]

Tall order for OO.. or is it to be static ?
