Question about original R-46 air-brake release |
|
Posted by railbus63 on Fri May 16 13:24:56 2008 I recall riding the subway during the early 1980's when the R-46's were still relatively new. Back then, they had a very unique air-brake release sound that I've never heard on another car in New York or on any other transit system. It started out as a high-pitched whistle and gradually faded. When I returned to railfan the subway after these cars had been rebuilt, they had the current brake release sound. Does anyone know what was done to the R-46 fleet to change this? |
