Locomotive safety system “ImProTRAIN-250”

Locomotive safety system “ImProTRAIN-250”

Statistically, the most common violations are:

passing a signal with a prohibitive aspect;
improper brake control;
exceeding speed limits.

On-board safety system ImProTRAIN-250 is one of the solutions to increase traffic safety and minimize the influence of the “human” factor.

The system assures the highest operating safety level in accordance with the requirements of industry standards, standards of the “1520 area” and the European Union.

Implementation of ImProTRAIN-250 on rolling stock will allow to:

Increase operating safety of rail traffic

due to a multileveled system aimed at monitoring train parameters, infrastructure, and a driver’s actions.

Improve locomotive availability

due to high reliability of the LSS equipment, which has dual and triple modular redundancy.

Significantly reduce labour and financial costs

for maintenance of traffic safety equipment.

Eliminate “paper technology”

through the use of a contactless electronic registration device.

Increase the time to take measures to stop a train in the event of a safety hazard

by using calculations that take into account the dynamics of the traffic and train characteristics (locomotive type, train weight, brake type, etc), which reduces the probability of material damage.

Optimize speed, save energy, fuel; and increase the lifetime of braking equipment.

Switch to predictive maintenance of safety equipment

due to self-diagnostics (without removing it from the locomotive and using external stands).

Key features

Versatility

– application for any type of rolling stock.

High survivability

– “single fault” tolerance due to deep self-diagnosis and reconfiguration (2оо3d → 2оо2d).

The frequency of occurrence of dangerous failures

does not exceed one in 70 thousand years.

Recording of all trip information

to a tamper proof contactless cassette and back up archive.

Availability of an archive of ALS

frequency signals with reference to coordinates for further analysis and diagnostics of signalling equipment.

Interaction with other on-board systems

via digital interfaces.

Communication with higher level systems via radio channel

(via the secure exchange protocol “EuroRadio” (UNISIG Subset 037)).

Cybersecurity.

Protected case and small dimensions.

User friendly interface.

Quick support and service provided by the manufacturer

for the entire life cycle of the system.

Main functions

Monitoring of train speed on a continuous basis and triggering emergency brake application

in case admissible maximum speed is exceeded

Prevention of passing signals with prohibitive aspects.

Prevention of unauthorized movement of a locomotive

(rolling down).

Generating a value of admissible maximum speed

of a train using ALSN signals, a radio channel, electronic map data.

Indication of distance to an actual obstacle

with the speed required to pass it (speed target).

Service brake application through a driver’s brake valve attachment on a command

transmitted through a digital radio channel.

Determination of speed and coordinates of a locomotive

based on information from satellite navigation devices and distance and speed sensors.

Driver’s vigilance monitoring.
