Great Indian Peninsula railway carriage, c 1871. Model (scale 1:12). Built entirely of teak, this carriage was fitted with an air cooling and ventilation system devised by R D Sanders in 1871. The cooling system worked by drawing air up through two wooden trunks beneath the carriage and forcing it over cloths kept constantly wet by a sprinkler pipe fed from a water tank fitted in the end of the carriage. On average this lowered the temperature by 15 degrees fahrenheit, with a water consumption of approximately six gallons per hour. Side view on plinth.
