Two J-3a locomotives were streamlined for service on trains #50/#51. Did these locomotives have lighting under the skirting to illuminate the drivers and valve gear?
The only locomotives that had floodlighted drivers were the two K-5b Pacifics that were streamlined for the Mercury. When the popular Mercury service resulted in trains too heavy for the Pacifics they were replaced by Hudsons. The streamlined Pacifics were re-assigned to the James Whitcomb Riley. I don't know whether or not they retained the lighting in that service. As far as I know, none of the Hudsons had any special lighting applied.
