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.
