Speed-torque curves show the results obtained from the steam afterit leaves the boiler, and they are of fundamental importance. Indicator diagrams furnish a record of the action of steam in thelocomotive cylinder. Many of the features of the indicator diagram ofthe steam locomotive are due to the variable speed requirements, andthe limitations of space between the ra
