Publication number: 20010029411Abstract: A method of optimizing train operation and training in a moving train includes determining the train's conditions and calculating a desired response to the present conditions of the train to achieve a goal. The engineer's response is determined and the train's conditions resulting from the engineer's response is determined and may be displayed on the train. The desired response, for example brake and propulsion settings, may be displayed after determining the engineer's response. The engineer is qualified from the comparison of the engineer's response to the desired response to the condition. Access to the locomotive controls may be controlled using a user identification and determining the qualification level of the user. The qualification level can be updated based on the training session.Type: ApplicationFiled: March 27, 2001Publication date: October 11, 2001Applicant: New York Air Brake CorporationInventor: Michael J.

Patent number: 6238010Abstract: An electropneumatic brake controller of the present invention including a main reservoir, pneumatic brake pipe relay and first and second restrictions connected in series with the main reservoir, the brake pipe relay and brake pipe and first electropneumatic valve connected in parallel to the second restriction. The second restriction is smaller than the first restriction. The first electropneumatic valve is responsive to an electric release signal to cut out the second restriction. When the two restrictions are in series, this is the running mode whereas when the second restriction is cut out, this is the release mode. A control unit controls the electropneumatic valves to produce an overcharge cycle in response to a release brake signal. This cycle includes overcharging the brake pipe, holding the overcharged condition for a fixed period of time and bleeding to a normal release brake pipe pressure.Type: GrantFiled: May 16, 2000Date of Patent: May 29, 2001Assignee: New York Air Brake CorporationInventors: Wayne H.

Patent number: 6172619Abstract: A method of serialization including establishing a parameter along a length of the train between a node on one of the cars and one end of the train. The presence or absence of the parameter at each node is determined and the parameter is removed. The sequence is repeated for each node on the train. Finally, serialization of the cars is determined as a function of the number of either determined presences or absences of the parameter for each node. The parameter can be established by providing at the individual node, one at a time, an electric load across an electric line running through the length of the train and measuring an electrical property, either current or voltage, at each node. The same process is used to determine the orientation of a car. The operability of each node is determined by counting the presence and then the absence of a parameter along the whole train.Type: GrantFiled: February 23, 1999Date of Patent: January 9, 2001Assignee: New York Air Brake CorporationInventors: Anthony W. Lumbis, Dale R. Stevens
