<p>The flanges of wheels of a railway vehicle are monitored for excess wear using an anvil block (20) supported by leaf springs (22) adjacent to the inside (14) of the rail head (13). A probe (25) projects above the block (20) such that a wheel flange (42) will push the anvil block (20) away from the rail (12). With such a block adjacent to each rail of a track at the same track position, the inter-flange spacing can be monitored for each wheelset. Such a block (20) may also carry an outer probe (32) which is pulled into contact with the outside of the falnge (42), at least one probe (32) being a flexible strip and providing signals indicating the separation of the probes (32 and 35), this giving an indication of flange thickness. When the wheel is not present, the outer probe (32) may locate in a recess (30) at the side of the rail head (13). Such an apparatus may be installed in a depot so every wheelset of every train can be monitored at frequent intervals.</p> |
