A dispensing adapter for connecting pressurized containers to other valved systems such as automobile air conditioners is provided. The housing has a dispensing end, a receiving end, and an interior volume communicating between the dispensing end and the receiving end. The receiving end sealingly engages a first valve of a pressurized container, and the dispensing end sealingly engages a second valve such as a service port of an automobile air conditioner. A reciprocatable core depressor is disposed inside the housing. When dispensing end is attached to the service port, the core depressor is moved toward the receiving end of the housing, and the proximal end of the core depressor engages a stem of the first valve and opens the first valve. The housing may be angled or straight, and the core depressor may have a piercing pin to open puncture valve containers.

A rail road car for carrying a wheeled vehicle, said rail road car comprising: a rail car body supported by railcar trucks for rolling motion in a longitudinal direction; said rail car body having a first end, a second end, and a deck for supporting the wheeled vehicle extending therebetween; a bridge plate mounted to said rail road car body to permit the wheeled vehicle to be conducted between said deck of said rail road car and a like rail road car coupled adjacent thereto, said bridge plate having an end portion located adjacent to said deck; and a transition plate mounted between said deck and said bridge plate to facilitate passage of the wheeled vehicle from said deck to said bridge plate; said transition plate being mounted to accommodate motion of said bridge plate relative to said deck while said rail road car is in motion. 2. The rail road car of claim 1 wherein said transition plate has a proximal portion mounted to said deck, and a distal portion resting upon said bridge plate. 3. The rail road car of claim 1 wherein said transition plate has a proximal portion hingedly mounted to said deck and a distal portion resting upon said bridge plate. 4. The rail road car of claim 3 wherein said proximal portion has an edge that extends cross-wise relative to said deck and said distal portion can be raised relative to said proximal portion, to a disengaged position relative to said bridge plate. 5. The rail road car of claim 1 wherein said transition plate is movable to a raised position clear of said bridge plate. 6. The rail road car of claim 5 wherein when said bridge plate is in said raised position, said bridge plate is movable to a cross-wise position relative to said rail road car. 7. The rail road car of claim 5 including a lifting member mounted to said car body, said lifting member having a first portion bearing on said transition plate, and a second portion at which a force can be applied to move said transition plate to said raised position. 8. The rail road car of claim 5 including a lifting member mounted to said car body, said lifting member having a first portion movable to bear against said transition plate, and a second portion extending laterally outboard of said rail car body at which an operator can apply an input force to urge said transition plate to said raised position. 9. The rail road car of claim 5 including a lifting crank, said crank having a shaft mounted to said car body, said shaft having an axis and being able to turn relative to said axis, a first member joined to said shaft and extending away from said axis, said first member having a surface movable to work against said transition plate as said shaft is turned, and said crank having a torque input member from which a torque can be transmitted to said shaft to turn said first member and to raise said transition plate. 10. The rail road car of claim 9 wherein said torque input member extends proud of said rail car body. 11. The rail road car of claim 9 wherein said rail car body includes side sills extending along either side of said deck, and said torque input member extends laterally proud of one of said side sills, whereby a person standing beside said rail road car can operate said crank to raise said transition plate. 12. The rail road car of claim 1 wherein: said end portion of said bridge plate is pivotally mounted to said rail road car body; and when said bridge plate is in said raised position, said bridge plate is pivotable to a cross-wise position relative to said rail road car body. 13. The railroad car of claim 1 wherein: rail road car includes a crank having a first shaft portion, a second, co-axial shaft portion, and a throw mounted between said first and second co-axial portions, said first and second shaft portions being mounted to said rail car body, and being rotatable to cause said throw to urge said transition plate to a disengaged position relative to said bridge plate. 14. The rail road
