Excerpt from The Berlin-Zossen Electric Railway Tests of 1903: A Report of the Test Runs Made on the Berlin-Zossen Railroad in the Months of September to November 1903 The energy spent in pulling a train over its track may be roughly divided into five elements: work against gravity, work of acceleration, internal resist ance that due to friction within the rolling-stock), external resistances, due to interaction between rolling-stock and track, and air resistance. Of these several items the first two, as such, are pretty definite in character and can be figured in a given case with reasonable precision. The last three are extremely hard to separate and have been the source of many difficulties. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
