KEEPING COOL IN THE SUBWAY

With cities in the tropics such as Caracas, Sao Paulo and Calcutta now building transit systems, the problem of keeping air temperatures in tunnels to a tolerable level is becoming more acute. Norman H. Danziger outlines the basic principles evolved to produce a satisfactory thermal balance on underground railways, part of a three-year research programme sponsored by the Institute for Rapid Transit. It has been found that trains account for between 85 and 90 percent of all the heat generated in a subway system. About half of this heat is caused by braking, the remainder largely by acceleration, traction, and vehicle air conditioning.
