I believe all SD60’s were built in the range of 390,000-420,000 lbs. with full supplies.
The dimensions on the Diesel Shop website for EMD units are often very wrong in my experience. The linked page for the SD60 has these errors:
Min RPM is 200 in low idle,
Traction Motor Blowers are mechanically driven off the engine as all EMD locos back to the GP30 are, not electrically driven, which came in with the SD70,
Weight might have been offered as light as 368,000 lbs. but I don’t believe any were built that light,
What is shown as starting tractive effort is actually the continuous TE of 98,250 lbs. The starting TE is 149,000 lbs.,
Not sure what SD50 is doing opposite Exterior Dimensions,
Total length of 71’-2" is correct over coupler pulling faces, Length over endplates is 67’-0",
Height to top of cab roof sheet is 14’-8.75", not 15’-7.5". This is the same height as the top of engine hood roof sheet. Height over cooling fans is 15’-7.12",
Top of walkway is 64.5" with 40" wheels, not 9’-4.5",
Walkway width is 24", not 3’-8.5",
Engine hood is 72" wide, not 10"-0",
“Center Bolster” dimension of 45’-10" is correct for distance between truck center bearings, (on the HTC truck, the center axle is outboard of the center bearing by 1.25")
Center bearings to end sheets is 10’-7" at both cab and hood ends, not 2’-3". The dimension from endplate to coupler pulling face is 25", an EMD standard for years.
