The invention provides a train lamp mounting frame body and a train provided with the same. The train lamp mounting frame body comprises a fixed support and a rotatable support, wherein the fixed support is used for connection with a train body, the rotatable support is rotatably connected to the fixed support around the preset axis direction, the rotatable support is used for installing a train lamp so as to make the train lamp adjustable with respect to a train body angle. Accordingly, after train lamp installation is completed, the irradiation angle of the train lamp can be flexibly, quickly and conveniently adjusted in the debugging process, and the problem is solved that a D-series high-speed train in the prior art consumes time and labor when the irradiation angle of the train lamp is adjusted at a debugging stage.
