Abstract: A guide rail and follower wheel construction for a monorail are disclosed. The monorail vehicle follower wheel has a radially directed, circumferential groove shaped to fit over a raised track portion, and the cross sectional shape of the wheel groove and the track over which it fits are such that the uppermost portion of the track contacts the radially innermost portion of the wheel groove. The wheel is mounted on the system comprising: a shaft and wheel includes opposed side-plates mounted for rotation on the shaft and a center disc mounted on the shaft between the side-plates and having a diameter less than that of the side-plates so as to form the groove. The side-plates are shaped to taper in diameter towards the center disc so that the uppermost track portion contacts only the disc. The side plates are rotatable on the shaft independently of the disc.

Abstract: A fish-plate comprises two sections which can be fitted, by way of a toothed surface, against corresponding toothed surfaces of two adjacent electrically conductive rails of a railway using bolts to tighten the sections towards each other. The teeth extend longitudinally, and the sections are vertically adjustable relatively to the rails to allow the fish-plate to be clamped to the rails at various heights.
