Abstract:
The technical feasibility of a heavy haul freight using WDPS (Wireless Distributed Power System) was verified for the first time in Korea. That consisted of a master locomotive, 50 freights and a slave locomotive. The master and slave locomotives were equipped with WDPS to distribute traction and braking control command data. MIMO-OFDM, which is strong in multi-path, was applied to the WDPS, and a repeater was installed on the 25th freight to secure coverage even with signal attenuation according to the terrain (curve, gradient) of the driving section. The test was carried out at an average sp

Abstract:
A series of methods for planning the use of train locomotives has been developed. However, existing scientific research does not clearly specify how the arrival and departure times of freight trains are determined in train schedules, and locomotives are assigned to trains based on the condition of “Locomotive waits for train”. This article proposes a methodology for determining the average time of stay for train locomotives and trains at the boundaries of train sidings for all scenarios ranging from the condition of “Train waits for locomotive” to “Locomotive waits for train”.

Abstract:
As freight trains are very frequently operated at night there is still big concern about freight train noise in Europe. Freight wagons in Switzerland and Germany are now all equipped with composite brake blocks instead of cast iron brake blocks which results in significant noise reductions. Using data from the Swiss noise monitoring stations the contribution of different locomotives to the overall train noise was evaluated. For locomotive types without cast iron brake blocks the year of construction is not related to the noise behavior. Newer types are not in general less noisy than old ones.

Abstract:
Electric locomotives with asynchronous traction drive are operated on the Russian road network in passenger and freight traffic. The advantage of such a drive is a large specific power. At first glance, electricity consumption of an electric locomotive with asynchronous traction drive should be less than that of an electric locomotive with a collector traction drive. The same is declared by manufacturers of traction rolling stock [1, 2]. But the answer to the question which electric locomotive is more economical in freight traffic: with a collector or asynchronous traction drive? - is far from

Accordingly, this work focused on reducing drag on lead locomotivesby designing and optimizing an add-on nose fairing that is feasible for industrial operation.The fairing shape design was performed via computational fluid dynamic (CFD) software.The simulations consiste
