Re: UP series 10300 to 12499

The UP B-50-24 and B-50-27 classes (including OWR&N and OSL) are noted as actively being
relettered in the 1963 ORER i.e. it was not yet completed by that time.

A good chance to reletter them came in 1962-1963 when the GRL (LD LMT + LT WT) numbers
for ALL freight cars had to be updated.

It’s hard to predict the future but I don’t think the OWR&N lettering will be used in the mid 1960s.

The cars are lettered as class B-50-41.  The prototype B-50-41 was a 1944 AAR box car with R/3/4 Early Improved Dreadnaught ends, and a diagonal panel roof.  These cars also had Alternating Center Rivets, which the model certainly does not have (few models do).  One could add them using Archer rivets, or one could do as I do and INTEND to add the Archer rivets someday… J


The number series for the B-50-41 in 1951 was 101600 – 105099, so these models fit that number series.
