Gate Accidents - A ‘Challenge’ Accepted
Based on ‘Radio communication’,
‘Microprocessors’ and ‘Global Positioning
System (GPS)’ technology, the Anti-Collision
devices at Level Crossing Gates and on board
Locomotives can apply brakes and/or alarm
the crew of the Train to apply brakes in time,
in case the Gate is open to road traffic or the
track area is obstructed by any vehicle.

Necessity
European approach to public safety and safety in the workplace as setout in the Framework Directive of the European Union (89/ 391/ EEC).This states that safety
“is an objective which should not be subordinated to purely economicconsiderations.”
A cost effective system for Railway Level Crossing Protection 5
Factors affecting probability of
collision of Road vehicle with train
at LC Gates1. Rail traffic density
2. Road traffic density
3. Visibility of the track, warning signs to road users.
4. Absence of full width barrier protection
5. Absence of Hooter & Flasher
6. Poor road surface condition
7. Poor alignment and elevation of road crossing
8. Whether conditions
9. Human error

‘ACD’ – A Solution against ‘Collision’ found…
• Anti-Collision Device (ACD) – A KRCL ‘Patent’
• Unique features – Prevents in a ‘mid-section’
– ‘Head-on’ Collisions
– ‘Side’ Collisions
– ‘Rear-end’ Collisions
– Accidents at Level Crossings
• No other Technology in the World supports
above features

‘ACD’ – Testing and validation
• Anti-Collision Device (ACD) – It has been validated by Electronic Test & Development Centre, Chennai, India.
• The product is tested and inspected by Lloyd
Register Asia (LRA, India) before dispatching
to the site.

GPS based wireless Level Crossing
Protection System
• A subset of ACD system with limited
functionality of Level Crossing protection
• Consists of Gate and Loco units with
redundant radio modems
• Repeaters required for ensuring
communication in the defined zone of 3Km.

Salient Features - What the system does
• ‘Train Approach’ Warning for road users at Level Crossings in the form of Audio Visual indication
• Detection of obstruction by road vehicle at level crossing
• Detection of Gate condition whether it is OPEN or CLOSED?
• Advance audio visual information to the train crew regarding the condition of the gate as detected by the Gate ACD.

Gate protection system CAN NOT Prevent a Train Collision when…
• The Train is a ‘NON’ ACD Train or Gate is not
provided with Gate ACD – ACD functions by
reacting to another ACD, as such if one of the two
identities is not provided with ACD, the protection
against collision will be missing
• ‘Adequate’ braking distance at that speed is not
available when a ‘dangerous’ collision-like situation
arises suddenly – However, severity of the collision
would be reduced as a function of the reaction time

Scenario – Gate OPEN
• Level Crossing Gate ST 346 is detected to be OPEN – Audio Visual Indication is automatically activated to draw the attention of the Driver and brakes are applied to reduce the speed to 15 Km/h.

System Adaptability
• Loco Unit can be provided in any type of Diesel or Electric Locomotive
• The Auto Braking Unit (ABU) is suitable for Air Brake/Vacuum brake/Computerised Control Braking systems
• Level Crossing Unit can be installed at any type of Gate working system to detect OPEN/CLOSE condition of gate
• Loco and Level Crossing Units are capable of withstanding -10 deg C to +70 Deg C temp variation

System Benefits
• It does not require any inputs to be fed by the crew at the start of journey, thus human error is eliminated.
• Very economical and cost effective• Easily adaptable and expandable• Does not degrade the existing safety level• Employs state-of-art hardware and software
technology• No way side equipment required, hence no
requirement of Power• No cabling on the track required (which is more
expensive and cumbersome)• Less susceptible to Vandalism.

GPS based wireless gate protection system Implementation Plan
• Survey & Route Design • Manufacturing and Installation of Units with
accessories• Commissioning of individual Loco & Gate Unit
installations• Training of Personnel • Configuration & Customization of the route • Commissioning of the Route• Post warranty Annual Maintenance (if required)
NOTE - System can be implemented in 1000 RKm track within one year after the order is received. This excludes installation in Locomotives which takes 12 hrs for each Locomotive at the shed.

Maintenance Support System (MSS)
• Daily Reports of incidences of Warning to the Driver due to Gate OPEN or Obstruction
• Date wise Report of incidences of Warning to the Driver due to Gate OPEN or Obstruction
• Daily Maintenance Report – Failure of Loco Unit and Gate Unit
• Date wise Maintenance Report – Failure of Loco Unit and Gate Unit
