A question for all the Union Pacific steam experts. When the UP #844 was in regular service until approx. 1962(not the 1962-now excursion engine versions), what color lens was used on the Mars light?
Red, just as it was originally installed about 1946.
Was the lens always red or was a clear lens also used during that time period?
Yes, always red. Just like the Milwaukee S3 Class 4-8-4s (#261 for example).
Thanks for the help
Nick
