Abstract Research purposes : The Baluntai - Kaitele Railway in Xinjiang is located in the high elevation area with high mountain，steep slope and complex topographical conditions. The most of planed tunnels for the railway will be the large tunnels with one after another. Selection of the reasonable main railway technical standards， such as traction type， limited gradient， locomotive type and tractive tonnage， is crncial to the constmction investment and the project operation. In this paper，the suitable main technical standards for this railway are presented for providing the reference to the similar works.
Research conclusions :(1) Based on the analysis of the various types of traction，it is recommended to use the electric locomotive. (2) Based on the analysis of the railway function orientation and the features of the traffic volume， it is recommended to adopt the balanced gradient scheme. Namely，the 6 ‰ limited gradient will be used for the heavy - haul direction and the 22‰ limited gradient will be used for light - haul direction. (3) In order to meet the demands of the tractive tonnage and the traffic capacity of this railway，it is recommended to use SS7 locomotive with the tractive tonnage of 3000t on consideration of the coordination with the adjacent railway network and making full use of the maintenance devices. (4) The demonstrations of the traffic security and the adaptability of the traffic organization show the main technical standards used for this railway are good in the operation and saving the construction investment. (5 ) The research result can be as the basis for the selection of the main technical standards for the mountain railway with the complex topographical conditions.
