Disclosed embodiments provide a system and methodologies that enable or improve a train operator's ability to detect when his train will or has switched tracks or routes automatically in response to the train switching tracks or route without input from the train operator. Disclosed embodiments enable automatic determination of a route that the train is currently on and the route the train is supposed to switch to and the ability to predict track/route switches before they occur. Thus, the disclosed embodiments are configured to more effectively provide proper driving instructions through the track/route change, instead of merely reacting to the track/route change.

The method further includes determining the number of responses during a present response interval and setting the length of a subsequent response interval as a function of the determined number of responses. The number of responses may be determined for a whole interval or for a portion of the present response interval, and the length of the subsequent response interval is set based on the response rate determined for the portion of the present response interval. The subsequent response interval may be initiated before the expiration of the present response interval if a new interval length is to be set.

The check valve permits flow from the brake pipe port to the reservoir port and prevents flow from the reservoir port to the brake pipe port independent of the piston.
