Abstract:
1. A system for processing diesel locomotive exhaust, the system comprising: an Emissions Control Unit (ECU) for processing locomotive exhaust; at least one parallel duct running parallel to train tracks the duct including an extendable and compressible inner duct residing in the at least one parallel duct and the extendable and compressible inner duct is adapted to extend and compress within the at least one parallel duct to allow movement of the locomotive along the train tracks; a slot forming a longitudinal opening into the at the least one parallel duct, the slot running substantially the length of the at the least one parallel duct; seals running the length of the slot and ordinarily closing the slot to resist the escape of exhaust emitted from a locomotive exhaust pipe from the at least one parallel duct; a duct transport unit adapted to slide along the at least one parallel duct and to open the seal as the duct transport unit slides along the at least one parallel duct, wherein the seal closes behind the duct transport unit; a bonnet for capturing the exhaust emitted from the locomotive exhaust pipe; a vertical duct connecting the bonnet to the duct transport unit carrying the captured exhaust from the bonnet to the duct transport unit; and a connecting duct connected to the at least one parallel duct for carrying the exhaust from the at least one parallel duct to the ECU.
