Posted by Train Dude on Fri May 16 20:59:00 2008, in response to Question about original R-46 air-brake release, posted by railbus63 on Fri May 16 13:24:56 2008. Even though the R-46 had P-Wire brake control back then, the pneumatic portion of the braking was pretty standard. As I recall, it was a Westcode brake package and the sound you heard on release was due to the port on the "J" Relay valve (or whatever Westcode called it). In 1990, the P-Wire system was eliminated and the brake package was replaced with a NYAB Brake package - same principle but the port on the "J" relay valve was of a different size. |
