Prospective designs of turnouts (1989)

A high-speed train is traveling along the railway tracks.

Leningradsky railway station in Moscow, they announce that the train is delayed.

Railway tracks.

Mechanism for switching switches.

Instrumental inspection and defectoscopy of switches show that a large number of switch units have worked out their standard service life and the permissible speed on them is significantly lower than the original.

Dispatching office of a railway junction.

The dispatcher reduces the speed of the train when passing a switch.

The most common switch units on the railway do not meet the requirements of today.

The grooved frogs used in them require the installation of a counter rail.

This rail causes intense horizontal and lateral forces, collisions of wheels with the counter rail, rails and switches.

A cartoon about the disadvantages of such switch units.

Examples of deformations of switch frogs are shown.

Their service life is several times less than that of other parts of the switch.

Design bureau of the Main Directorate of Track.

Designers together with scientists have developed a fundamentally new design of a switch unit with a continuous rolling surface.

The crossing has undergone the greatest changes.

Equipment at the testing ground.

Conventional turnouts ensure the movement of trains at a speed of no more than 140 km / h.

High-speed turnouts are designed for the movement of trains at higher speeds of 200-250 km / h.

Special switches are designed for movement at higher speeds on a side track.

A train is moving.

Special switches with a turning core have been developed for tracks with high freight traffic.

Preliminary assembly of special switches.

Old switches are removed.

New switches are installed in place of the old ones.

Rack assembly of switch switches ensures their high quality.

Installation of switch switches on the track.

All switch switches are equipped with position control included in the electrical interlocking circuits.

Dispatch.

A special workshop has been put into operation at the Murom Switch Plant for the serial production of switch switches.

New technologies have been introduced here, and a number of labor-intensive processes have been automated.

Alternation of personnel from the production of switch switches.

Guardrails are made of special rolled rails.

This allows us to abandon the highly scarce manganese steel.

CNC machines are used in production.

Surface hardening is carried out with high-frequency currents.

Crosspieces are assembled on a special stand.

The accuracy of the assembly is checked with comparative templates.

Large-scale, workers of the enterprise.

The switch assembly stand allows simulating working conditions on the way.

Switches with a continuous rolling surface can save the state a lot of money.
