Finally, the resist-ance of a single car is very different from that of a train ofcars such as used in most of the published tests. The first comprehensive tests to determine the resistance ofelectric cars at high speeds and the effect on the resistance ofvarying the number of cars in a train were made by the writerin March, 1900, on a section of the Buffalo & Lockport Rail-way. The coasting method was used in making the tests andthe resistance for each set of conditions obtained from speed-time and speed-distance coasting curves as furnis
