H-6, H-8 and R4-RL Brake Valves on Engines

[NW Mailing List]

I defer to Mr. King on the answer to the first question.

In connection with the second question, The RS-3's, RS-11's (Road Numbers 309 through 364) and GP-9's (Road Numbers 500 through 505 and 710 through 842) were built with 24RL.  The GP-7's inherited from the Nickel Plate and Wabash had No. 6 equipment.

There were some Nickel Plate and Wabash switchers that had 14-EL equipment.
