Traveling duct for carrying exhaust captured from moving diesel-powered locomotives

A system for capturing and processing exhaust from a moving vehicle, the system comprising:

• an Emissions Control Unit (ECU) configured to reduce pollutants in engine exhaust flowing through the ECU;
• a stationary horizontal duct including a lengthwise running slot and residing along a vehicle path, the horizontal duct in fluid communication with the ECU;
• a bonnet for capturing exhaust from the moving vehicle;
• a vertical duct for placing the bonnet in fluid communication with the horizontal duct through the slot, wherein the vertical duct is adapted to translate along the horizontal duct, and is positionable to allow positioning the bonnet over an exhaust pipe of the vehicle for capturing exhaust from the moving vehicle, the ECU processing the exhaust to reduce pollutants in the exhaust before the exhaust is released to the atmosphere;
• a duct transport unit translating along the horizontal duct with the vertical duct and interfacing the vertical duct to the horizontal duct;
• and
• two longitudinally extending rows of side by side tiles residing in the stationary horizontal duct, the two rows of tiles opposing each other and sliding laterally together to close before and after the duct transport unit for sealing the lengthwise running slot in front of the duct transport unit and behind the duct transport unit, the tiles including tile bumpers and the duct transport unit including a transport unit bumper, wherein the transport unit bumper cooperates with the tile bumpers to push the opposing tiles apart as the duct transport unit moves along the horizontal duct.

• a duct transport unit translating along the length of the horizontal duct with the vertical duct and interfacing the vertical duct to the horizontal duct;
• and
• two longitudinally extending rows of side by side tiles residing in the stationary horizontal duct, the two rows of tiles opposing each other and sliding laterally together to close before and after the duct transport unit for sealing the lengthwise running slot in front of the duct transport unit and behind the duct transport unit, opposing faces of the tiles meeting to close the slot, the opposing faces having cooperating bevels, wherein one of the opposing faces includes a beveled underface facing up and the other one of the opposing faces includes a beveled overface facing down, and when the opposing tiles close, the beveled faces overlap to laterally close the slot.
