Research of geometric parameters of symmetric railroad switches [PDF]

MATEC Web of Conferences
Turnouts are a barrier in the track for setting the permissible speeds of trains movements on the main tracks, as they have special structural devices for branching traffic from the main track to the side one.

Revisiting the reasons for contact fatigue defects in rails

MATEC Web of Conferences, 2017
As it is known rail is one of the most significant elements of the whole railway construction. Operation under alternating loads from wheels of the rolling stock and different ambient temperatures lead to appearance and development of rail defects and ...

A longer service life of intermediate elastic fastenings KPP-5 due to application of pads PRP-3.2

MATEC Web of Conferences, 2018
Since 2003 Ukrainian railways have used KPP-5 intermediate elastic fastenings. These fastenings unlike their predecessors (for example, terminal-bolted fastenings (KB) widely used on railways), first of all, have fewer elements.

A mathematical model of the rail track presented as a bar on elastic and dissipative supports under the influence of moving loads

MATEC Web of Conferences, 2017
At present, the most common track model is the one in which rails are presented as bars of infinite length rested on continuous elastic foundation. However, some specialists consider the model to be rather ideal for railways in terms of track and the ...

Study of the predominant defect development in rails of underground systems after preventive grinding and lubrication

MATEC Web of Conferences, 2017
In order to determine the method of contact surface treatment and to define the rational surface roughness in the wheel/rail contact for the minimal growth rate of contact fatigue defects the program of experiments in operational conditions was developed.
