Reports.[1][2]


Mention must not be omitted of the interesting brake trials at Welbeck Park on the 11th January 1902, with the object of providing trustworthy data for the instruction of the Local Government Board, whose chief engineering inspector was present. After systematic experiments, officially timed and measured, the following were found to be the distances within which cars could be brought to a standstill:-

  • From 11 to 14 miles per hour in 1.8 time the car's length;
  • From 15 to 17 miles per hour in twice the car's length;
  • From 18 to 20 miles per hour in 2.75 times the car's length;
  • From 20 to 24 miles per hour in 3.5 times the car's length.
