Cooperation of switch drives with high-speed turnout switches

Abstract: The article discusses the cooperation of a switch drive with the Rz 60E1-760-1:14 turnout switch equipped with a mechanical coupling of setting locks in the standard and Integrated Roding versions. The use of turnouts with a greater number of setting locks is correlated with the need to use turnouts with large angles and radii, enabling high-speed travel through the turnout.1. INTRODUCTION
The pursuit of improving the state of railway infrastructure in Poland, along with increasing permissible travel speeds, is inextricably linked to changes in the design and technical parameters of turnouts. One example of the development of new types of turnouts is the introduction into service of Rz 60E1-760-1:14 turnouts with a 1:40 inclination.
This is a type of turnout that can be operated as a turnout with multi-drive control (the switch of this turnout is equipped with three setting locks) or as a system with single-drive control with mechanical coupling of setting locks (this coupling can be made as an SPZ-60 coupling, or in a special turnout design as an Integrated Roding coupling). The article presents a comparison of the results of tests carried out on the
Rz 60E1-760-1:14 turnout with a 1:40 inclination in two configurations:
1. with the 60E1-760-1:14 sb turnout switch, standard version, 2. with the 60E1-760-1:14 sb turnout switch, “Integrated Roding” version, with mechanical coupling of setting locks.
From the point of view of the control system, a very important parameter of the cooperation between the switch drive and the turnout switch is the mutual interaction of these two elements under shifting conditions (shifting resistance) as well as under static conditions (spring force of the switch rails).
