A differenee of 3464 inches in the gauge of railroad tracks in Western Europe
and the soviet area created thelroblem of making axle adjustments. Boviet
tracks had a gauge of 1324 Mm whereat Western European tracks had a otuipt of
1435 mm. This difference necessitated an adjustment of 1.752 inches por wheel,

2. The Railroad Administration of Latvia had technical standards fin wheal and axle
sets which showed the minimum pressure between axle and hub. When the pressure
between the hub and the axle became too low) the wheel had to be removed. The
inside of the hub hole had to be welded electrically and turned out on a right
interval diameter (Fig 2). A wheel so prepared was then ready for assembly.

3. A two-axle freight car standing on the assembly line was lifted by mean& of
pneumatic jacks. The wheel and axle sets were rolled out and sent to the wheel,
axle shop. This was to avoid mixing up axle bearings; the same bearings had to
be used on the same axle. The wheel and axle sets could be interchanged, but
the thickness of the rim of the wheels had to be the same (Fig 3).

If the freight car were equipped with brakes1 the brake triangle had tc be changed
accordingly and the brakes re-located (Fig 4).

The number of men required to perform this operation depended upon the degree of
skill available and the technical equipment on hand.

5. The length of time required to change width for narrow or broad gauge tracks also
depended on the technical equipment on hand. It was usually between 100 and 150
hours.
6. There was no limit to the number of times the same wheel and axle set could be
regauged because the hub could be welded. Sometimes the pressure between the axle
and the hub was too great and the surface of the axle was scratched. Such axles
were turned down on a lathe and used on lighter weight cars. (The European two-
axle cars ranged in capacity from 10 to 20 tons.) Differences in capacity were
determined by the diameters, of the axles.

50X1 is no way to determine whether adjustable axles were discarded or what type of
substitute is now in use. The method described above was in use from 1940-1944, in
addition to the use of the adjustable axle 50X1
