A railway truck frame for a railway truck including a first side frame and a second side frame, each side frame having an inverted trapezoidal-shaped window including a first inclined side and a second inclined side. The truck frame also includes a bolster having a first end and a second end which extends transversely between the first and second side frames. Each end of the bolster includes a first inclined channel and an opposing second inclined channel. Each channel includes an exterior flange, a spaced apart interior flange, and a bearing surface located between the exterior and the interior flanges. Each inclined side of a window is adapted to be located in a respective first or second channel between the exterior flange and the interior flange of the channel and in engagement with the bearing surface of the channel. A locking device such as a jack is located in each window between the top of the end of the bolster and the top side of the window which selectively forces the end of the bolster downwardly into engagement with the side frame such that the end of the bolster is rigidly but removably connected to the side frame.
