Determination of wagon-hours accumulation economy during wagon group exchange in the double-block train

The solution for a problem of determination of reducing the idle time wagon-hours for wagons in marshalling tracks, using the possible variants of work technology with the double-block train at a station of exchange groups, is proposed. The formulas for determination of reducing the idle time of wagons under accumulation, using each variants of implementing the exchange of wagon groups in the double-block train are obtained.
