GASOLINE MOTOR INSPECTION CARS. The use of inspection cars operated by gasoline engineshas been favorably considered on many railroads, both steamand electric. Because of the fact that such cars can operate. Gasoline Inspection Car. at comparatively high speeds, irrespective of power conditions,they are found to be of considerable use for inspection pur-poses and night work that must be done after the power isshut off. The accompanying illustration shows a type of carmanufactured for Fairbanks. Morse & Co. On one of thesecars an interesting record recently was made on the MichiganCentral Railroad. It is stated that in a total mileage of there were used gallons of gasoline and gallonsot lubricating oil. Especially fast runs were, miles in1 hour and 40 minutes, and miles in 45 minutes, or atrates of 40 and miles per hour, respectively. rno ELECTRIC RAILWAY REVIEW Vol. XVIIl, Xu. IS.
