LONDON TRANSPORT RAIL DE-STRESSER

A new device was designed for de-stressing long-welded rail after any disturbance to them in cold weather. The machine, a rail-heating trolley is so geared that it is easily propelled along the track by one man at the low operating speed required--about 2 mile/h. At each corner of the trolley is carried a 100-lb bottle of propane, and from these, flexible hoses run to the rail heaters. The equipment is designed for use on the open sections of line. De-stressing is not necessary in tunnels as the temperature remains almost constant throughout the year. On open lines, rails are de-stressed after they are installed, and it is only necessary then to de-stress them again when they have been disturbing for changing a block-joint or resleepering outside the mid-range temperature.
