A well car includes a well floor, a first end portion, a second end portion, and a first side assembly. The first end is portion coupled to the well floor. The second end portion is coupled to the well floor. The first side assembly is coupled to the well floor. The first side assembly includes a first side portion, a second side portion, and a first humped portion coupled between the first and second side portions. The first side portion is coupled to the first end portion. The second side portion is coupled to the second end portion. The first humped portion is positioned higher than the first and second portions on the first side assembly.

According to some embodiments, a modular railcar comprises: a pair of trucks disposed near each end of the modular railcar; an underframe coupled to the pair of trucks and supported by the pair of trucks. The underframe comprises a plurality of coupling apparatus. The plurality of coupling apparatus are configured to couple a modular top container to the underframe. According to some embodiments, a modular top container comprises: a floor panel configured to transport a lading; and a plurality of coupling apparatus coupled to the floor panel. The plurality of coupling apparatus are configured to couple the modular top container to a modular railcar. The floor panel is configured to support the weight of the lading when detached from the modular railcar.

A railcar includes a first panel, a second panel, and a bottom surface. The second side panel opposes the first side panel and is substantially parallel to the first side panel. The bottom surface includes a first beam and a second beam. The first beam is coupled to the first side panel and the second side panel. The first beam is substantially parallel to a normal of the first side panel and to a normal of the second side panel. The second beam is coupled to the first side panel and the second side panel such that the second beam is adjacent to the first beam and such that the second beam forms less than a ninety-degree angle with the first beam. the first beam and the second beam define an open space in the bottom surface.

A rail vehicle, in particular a locomotive, has at least one bogie with a bogie frame supported resiliently on sets of wheels, and a superstructure, which is supported resiliently on the at least one bogie and is mounted rotatably about a vertical axis, with a under frame. A removal device for removing snow and/or ice is arranged between the under frame and the bogie frame. The removal device has an inclined sliding surface which at least partially covers the bogie frame. Deposits of snow and/or ice both on the bogie frame and on the under frame of the superstructure can thereby be prevented or eliminated.

A train made up of a plurality of rail vehicles, each rail vehicle including a body defining an upper level able and intended to accommodate and transport passengers, and a lower level intended to load, transport and unload freight, the lower level having a lower floor defined by the body. An assembly of such a train, and a station able to receive the train in a stopped position allowing travelers to embark and disembark.

A mounting structure for equipment compartment bottom plate is provided. The bottom plate is detachably connected to a skeleton boundary beam of the equipment compartment. A sliding rail is fixedly connected to a side of the bottom plate where the bottom plate is lap-jointed to a skeleton lateral beam of the equipment compartment. One of the sliding rail and the skeleton lateral beam is provided with a recess and the other is provided with a protrusion engaged with the recess. In the mounting structure, the connection of the bottom plate and the skeleton lateral beam is achieved by the engagement of the recess and the protrusion. Therefore, connecting pieces for connecting the bottom plate and the skeleton lateral beam are removed and the number of the connecting pieces is significantly reduced.
