Chapter III: Equipment

A curious and somewhat ingenious Japanese armored vehicle is the Model 93 (1933) Sumida, sometimes called the "armored trolley car", since, by changing wheel rims, it can be used either as a car or an armored "trolley" on railway lines. To change it from a rail to road vehicle, the car is raised by four built-in jacks. The flanged steel tires are removed and solid-rubber tires then are placed over the wheels, an operation taking 10 to 20 minutes. The vehicle then can be driven off the rails onto the road. Substitution of the flanged tires for rubber tires adapts it for rail use. When traveling the set of tires not in use is attached to the sides of the hull.

The engine is in front, and there is a round cupola on the van-shaped hull. Road speed is estimated at about 25 miles per hour, but on rails the vehicle can attain a speed of about 40 miles per hour. Maximum armor thickness is 0.63 inch. The car is armed with one or more heavy machine guns, and there are seven rifle slits.
