Hi Fellow;

This is the same a spot for the a also give for the wheel bore.
This F7 era should be the same a EMD MRS-1 built 13 in 1952 with was built with a mulit-gage
truck the a hollow axle in the center of the axle(for ono-to-opp-side.) We need
the determine the bore before we take the truck apart a change 6 axle with ALCo
RSX-4 MRS1 axles.
The dimension should be the F7 in caliper type so we can compare with the ALCo RSX-1 MRS
with we have a site.

AAR say no axle will the hollow and shop with not press wheel on/off.

The is for Pacific Southwest Railway Museum.
