Contribution of a tunnel to train-running energy consumption for Nakhon Sawan – Mae Sot Railway Line Project

This article presents a study of a single train movement with tunnel effect on train-running energy consumption. The Nakhon Sawan-Mae Sot double track railway project has been selected as a test section. Simulation was done on a single train traveling whole trip from Nakhon Sawan through Khamphaeng Phet, Tak and Mae Sot with 27 passenger stations in 247.085 km range including 4 tunnels, 2 twin tunnels and 2 single tunnels with overall length 29.714 km. Simulation work was divided into 2 scenarios namely city train traveling with higher number of stops and express train with a few stops. It also noted that this study excluded gradient in this study.
