EMD Loco Wheelbase and Coupled Length

Note: these are the Prototype dimensions, model dimensions may vary

Additions welcome. Other List Subjects also solicited.

This is a general list of EMD Locomotives, their wheel base and coupled length.

I compiled this list approx. 12 years ago, so is a little out of date. Most of the wheel base dimensions are likely correct, the coupled length, is actually the dimension through the coupler mating surfaces.

The figures are taken from HO Scale Plans published in mainstream magazines, the coupled length has been used as the standard, as not all gave the pilot to pilot dimension. Treat this dimension in the table below with great caution.

As a general Rule of Thumb - you should be able to subtract approx. 4ft from the coupled length, to get the pilot to pilot measurement. Most Plans seem to indicate the coupler mating surface extending 25in from the pilot. This will likely vary on cab units with extending pilots.

I developed this list, to help in my kitbashing, even though SP had no eg. BL2's, that chassis with a 35ft wheelbase may be usable for something else.

Remember - always measure twice, and cut once...
