SIMULTANEOUS BOTH TRACK OCCUPATION

Abstract

The efficacy of maintenance of track and structures at the railway sections with intensive freight traffic can be augmented by rational redistribution of repair works. Favorable conditions can be achieved particularly by according simultaneous both track occupation at double-track rail sections. The authors describe practices of track maintenance at Kuibyshevskaya railway – a subsidiary to JSC Russian Railways as compared to international expertise.

Some railways, for instance in People’s Republic of China, widely practice such 3-hours track occupations, thus allowing to do all necessary works, e. g. to replace singular rails, sleepers, elements of switches, to proceed with straightening and aligning of the track etc.

The authors have analyzed possibility to provide such track occupations at the network of Kuibyshevskaya railway. They have made a conclusion that there is a possibility to provide them all along the main track from Rybnoe to Chelyabinsk for 2–3 hours. In 85% of cases there is a possibility to provide them during day-time, and in 15% cases – during night-time.
