Owen,
It would appear you have attempted to translate your post into English from some other language..
You need to find a different program to use for your translation!
Because this post makes no sense at all..sorry.
Do you have something else you can use for translation and try again?

(Owen S. Paulsen-- I'm sorry. I cannot understand your post. Can you get an English speaking friend to help you rewrite it?)

The truck (bogie) on the EMD MRS-1 locomotive is very different from that used on EMD's SD-7 (etc) locomotives: it looks much more like the truck used by Alco on its 6-axle, Co-Co, locomotives.

QUESTION: Is the truck on the EMD MRS-1 the same design as that on Alco's MRS-1 ???

The spacing between the axles ("length" between axles: O.S.P., did you mean "length" when you wrote "lathe"?) on the MRS-1 truck is uneven. The spacing on the truck used on the SD series of locomotives (up to 1972) is symmetric: distance from the front axle to the centre axle is the same as distance from the centre axle to the rear axle: 6 feet, 9.5 inches.

EMD developed the truck used on the SD series locomotives partly in response to a request from Victorian Railways (Australia): it (or a variant) was used on VR's ML-2 locomotives. The first ML-2 and first SD-7 were both built in 1952, the same year as EMD's MRS-1 locomotive. The MRS-1 was built for the United States Army: its design (including the type of truck used) may have been specified in a contract with the Army before the SD truck was available.
