Сколько весил первый в мире паровой локомотив?
Stephenson designed "Rocket" for the Rainhill Trials, and the specific rules of that contest. As the first railway intended for passengers more than freight, the rules emphasised speed and would require reliability, but the weight of the locomotive was also tightly restricted. Six-wheeled locomotives were limited to six tons, four-wheeled locomotives to four and a half tons. In particular, the weight of the train expected to be hauled was to be no more than three times the actual weight of the locomotive. Stephenson realised that whatever the size of previously successful locomotives, this new contest would favour a fast, light locomotive of only moderate hauling power.
