[quote user="kolechovski"] But the air still has to go through the service reservoir to get to the brake cyclinder, right?  Or is there now a direct connection from the train line to the brake cylinder available with ECP?  And with graduated release given by ECP, will railcars made new even be equipped with retainers anymore?  After all, they'd be useless now, right? [/quote] The service reservoirs and brake cylinders have the same relationship to each other with ECP that they have with conventional air brakes.  But with conventional brakes, a pneumatically controlled valve allowed air to move from the reservoirs to the brake cylinder.  Whereas, with ECP brakes, an electrically controlled valve replaces the pneumatically controlled valve of conventional brakes.  With ECP brakes, the graduated release function can perform the function of retainers.  Retainers are a way to overcome the inability of conventional air brakes to allow graduated release.  I may be wrong, but I thought retainers were still on all freight cars, and could be used if needed.
