The look at 1600 HP with 3 Axle and 3 motor.

Do anybody measure the space between the 3 Axle and see if the spaced to (1) Axle to middle (2) Axle is 6'-11" the loading pad and from middle Axle to (3) Axle it 5'-7" with has swivel plate.

I need distant from swivel plate to middle (2)Axle an 5'-7" to see I
can use standard gauge instead multi-gauge,I also need see where load pad from middle (2) Axle in 6'-11".

This could save money:
No buy long Axle.
Get roller bear,Do not that box a modify.
I do not Traction motors, The unit equipment type 5GE731F1.
The for complete except Traction motor.

I need to know the 1600 HP and 3 motor is O.K., an Where,What type
Locomotive that on.
