A detection and positioning method for a train water injection port includes: acquiring train water injection port video images, and performing threshold segmentation on the train water injection port video images to obtain binarized train water injection port video images; processing the binarized train water injection port video images and matching the processed binarized train water injection port video images with a train water injection port template image; detecting a position of the water injection port in the train water injection port video image and comparing the position with a pre-set position range where the water injection port is located; and if the position and the pre-set position range have been matched, then transmitting a matching valid signal to a mechanical device control module to control a mechanical device to move or stop and start or stop water injection.

Various techniques are provided for an expandable energy absorbing fluid bladder. In one example, the fluid bladder includes a primary portion and a secondary portion. The secondary portion can be configured to expand or increase in volume when the fluid bladder is subjected to a pulse greater than a threshold pulse. Expansion of the secondary portion can allow fluid or additional fluid to flow into the secondary portion and thus decrease a peak pulse and, thus, avoid rupture of the fluid bladder.

A rail vehicle includes a fuel tank having a tank wall delimiting a tank interior space for storing fuel. At least portions of a first support are connected to the tank wall. A longitudinal support includes first and second longitudinal support portions being offset in longitudinal direction of the vehicle. The fuel tank is disposed in longitudinal direction between the first and second longitudinal support portions. The first support is coupled to the first and second longitudinal support portions. At least portions of the first support are disposed in the tank interior space in the longitudinal direction. The first support running in the longitudinal direction is disposed between the first and second longitudinal support portions. The first support is configured for fully transmitting a force acting between the first and second longitudinal support portions in longitudinal direction of the vehicle.

A dual-fuel tank houses one or more compressed natural gas (CNG) vessels and one or more diesel fuel vessels. The diesel fuel vessels are generally disposed laterally outwardly from the CNG vessels to provide a buffer that protects the CNG vessels from side impacts. The dual-fuel tank may be retrofit onto a diesel locomotive in place of the locomotive's diesel fuel tank to convert the locomotive into a dual-fuel locomotive. The dual-fuel tank may be provided in a ship.

A railway traction vehicle comprising a plurality of axles, a fuel gas power unit (112), a fuel gas storage assembly (118) including a predetermined number of fuel gas storage modules (122), and a fuel gas delivery network (120). The fuel gas storage assembly (118) comprises a plurality of identical fuel gas storage module receiving devices (124), and, for each of said receiving devices, an identical fuel gas coupling (126) for coupling a module (122) with said network (120). The modules (122) share a standardised configuration such that each of them can be received in any of said receiving devices (124) and coupled to the corresponding fuel gas coupling (126). They are distributed over said fuel gas storage module receiving devices (124) such that the load on the axles is optimised. The predetermined number is adapted to the amount of fuel gas needed by the vehicle to operate on a predetermined railway line. Preferred application to regional passenger multiple units.
