Supports and fittings for points at wall corners on building construction railway have sleepers placed along wall and at points

摘要

The railway may be a monorail, laid along the line of a wall to be constructed. Straight sections of track meet and cross at the corners of the wall and there are points with a curve cutting across the corner to allow through -running of a carriage. The straight lines (9) rest on sleeper blocks (10) which lie between the two faces of (7,8) of the wall. A calibration device has an edge (11) coincident with an edge of the wall.
