A platform arrangement for an end structure of a railway well car having a well portion defined by spaced apart side structures, opposing end structures and a floor structure extending between the side structures. Each of the end structures has spaced apart sidewalls, with a horizontally disposed shear plate extending between and connecting to the sidewalls. Each of the end structures further includes (i) an upper bolster extending upwardly from the shear plate and connecting to the sidewalls; (ii) a bulkhead depending from an inboard end of the shear plate, which extends into the well portion and between the sidewalls to connect to them; and (iii) a stub centre sill positioned below the shear plate. The platform arrangement itself comprises (i) a first horizontal platform surface; (ii) a second horizontal platform surface; (iii) an outboard intermediate horizontal platform surface; (iv) an inboard intermediate horizontal platform surface; and (v) a foothold provided with the bulkhead. The first and second horizontal platforms surface extend transversely of the well car. The first is disposed at a position outboard of the upper bolster; the second is disposed immediately above the upper bolster. The outboard intermediate platform is disposed above the first platform and below the second platformat a position outboard of the upper bolster. The inboard intermediate platform is disposed below the second platform and above the shear plate at a position inboard of the upper bolster member. The foothold is located at a vertical position intermediate of the shear plate and the floor structure. The platform arrangement constitutes means for accessing the well portion of the well car from ground level by successively stepping onto the first platform, the outboard intermediate platform, the second platform, the inboard intermediate platform, the shear plate and the foothold.
