The invention discloses a railway transportation vehicle unit of multi-specification large-tonnage precast girders. The railway transportation vehicle unit comprises a head vehicle and a tail vehicle, wherein the head vehicle adopts the same main-body structure as the tail vehicle; a plurality of fixing positions for bridge-girder supporting devices are arranged on the head vehicle, and a plurality of fixing positions for bridge-girder supporting devices are arranged on the tail vehicle; the transportation of multi-specification precast girders is realized by moving the fixing positions of the bridge-girder supporting devices on the head vehicle and the tail vehicle. The railway transportation vehicle unit disclosed by the invention can transport precast girders of 16m, 24m, 32m, and the like, which are close to length specifications, and has multiple functions; the head vehicle and the tail vehicle adopt steel-floor structures, positioning holes are formed in steel floors, the steel floors are made by a mold and have interchangeability, and the positions of steering wheel holders and the positions of the bridge-girder supporting devices are convenient to change; major configurations of the head vehicle, major configurations of the tail vehicle, and major configurations of a middle railway wagon adopt a convention mature technology, and are high in reliability; when the railway transportation vehicle unit does not transport girders, any of the head vehicle, the tail vehicle and the middle random vehicle can be used as a common flat vehicle, so that the application of the railway transportation vehicle unit is flexible.
