Base data for trains


This page explains the base data for trains. As this simulation was done on a private initiative these data were gathered in the internet and do need verification, as they have a major impact on the results.

circleRadius [KM] the radius of 100 km is arbitrarily chosen. It can be any other radius

speed outside of circle  100 km/h  arbitrarily chosen to make travel to circle 1 hour, allows easy control of the rides.

speed on circle  156 km/h  This speed is chosen in order to have a train passing a quarter of a circle in 1 hour. This allows easy control of the train ride results.

Curbweight freight  = 1 ton / MeterTrainlength  This data was conservatively choosen based on long discussion with train specialists who mentioned hundreds of details. Therefore this is one of the major parameters to discuss.

Payload freight [tons/MeterTrainlength] 1.5 tons per MeterTrainlength. Same story as for the curbweight

Energy consumed to move 1 ton of freight 1 Meter  1 Kilojoule per MeterTon of freight

Payload People 4 [People / MeterTrainlength]

Energy consumed to move 1 ton of People 1 Meter  0.5 Kilojoule per MeterTon

The best input was found in a study TBD add reference of the Swiss Railway corporation, the pase parameter for energy consumed base on that study.

However these results base on the energy consumption of ‘traditional’ train runs, containing still a lot of elder model with higher energy consumption and less light weight with more efficient traction units. The train runs also have frequent phases of high acceleration and braking, frequent velocity variation and little use of eddy current brake which leads to a consumption that is significantly higher then a train running with constant speed, as it is for the car running on a high way with moderate constant speed.

If you have input like public results from newer train systems, research results of studies, please give you input using the feedback form.
