CHAPTER 1
1 GENERAL
1.1 Introduction
1.1.1 Indian Railways have decided to induct Self Propelled Accident Relief Trains (SPART) with
speed potential of 160 kmph, with a view to putting in place a fast and reliable disaster
management system.
1.1.2 SPART are trainsets required to proceed to accident sites and are located at important
yards and stations on Indian Railways (IR) at vantage locations so as to be able reach the
accident spot for rescue and relief work at very short notice.
1.1.3 This specification outlines the requirement for SPART to be procured for Indian Railways.
The Contractor shall design, manufacture, test and deliver the SPART as described by this
specification.
1.2 General Information
1.2.1 Accident Relief on IR
1.2.1.1 The Indian Railways is having an organized system of relief for managing accidents with its
own resources. In most of the countries in the unfortunate event of Railway accident, relief
and rescue work is spearheaded by civil authorities as in case of road accidents. However,
on Indian Railways, all the rescue and relief work is carried over by Railways.
1.2.1.2 Presently, 161 ARMVs (Accident Relief Medical Van) and 206 ARTs, (Accident Relief Train)
are positioned at strategic locations which cover the entire rail network of Indian Railways
for rushing to accident sites on top priority, along with doctors, paramedical staff, rescue
workers and engineers. Many ARTs also have 140 Ton Diesel Hydraulic crane attached to
them.
1.2.1.3 The accident is reported by the guard or loco pilot of the train to the nearest station or
divisional control room and the nearest railway stations, through telephone sockets
provided at the poles alongside the railway track. The control gauges the extent of
requirement of relief operations and dispatches the ART and ARMV as per requirement.
Effective communication and response time is of essence. The idea is to reach the spot as
early as possible so as to provide medical relief in the 'Golden Hour'. The existing layout
has provision of 22 berths in the supervisor van however the Indian Railway guidelines say
that as many trained staff are to be sent with the relief train as possible. Staff would
include team of doctors and paramedics like stretcher bearers, dressers, assistants for
boiling instruments in water to keep in readiness etc.
1.2.2 SPART Requirement
1.2.2.1 For faster initial response and for providing quickest possible medical attention and
restoration, it is planned to induct Self Propelled Accident Relief Trains (SPART) capable of
160 kmph speed on IR system.
1.2.2.2 These will be located at strategic locations so as to cover an area not beyond a distance of
150 to 200 kms within 1 to 2 hours normally.
13
1.2.2.3 On receiving information of an accident, SPART will be dispatched to the accident site
along with personnel trained in rescue and relief operations. Target time for dispatch of
SPART is a maximum 20 minutes from their ordering.
1.2.2.4 The function of the SPART is to carry medical equipment to the accident site so that
prompt medical aid could be rendered and injured persons transported expeditiously to
the nearest hospitals.
1.2.2.5 The SPART will have provision for emergency tools for extricating passengers from debris.
Hydraulic Rescue Device (HRD) like Cutters with accessories, Hydraulic pump with
generator, Manual pump, hoses etc. ; Hydraulic Rerailing Equipment (HRE) like Jacks with
hoses, Rerailing bridges and other Equipment like Ladders, Gas Cutters, Lights, Misc. tools,
Inflatable Air Bag etc. are provided in Tool Van (Detail tool list provided at Annexure E ). .
1.2.2.6 Operation Theatre in medical van is provided for emergency surgery with facilities for
tracheotomy, venesection, amputations and other life saving procedures. It also has a state
of the art anesthesia apparatus, defibrillator, pulse oxymeter and a cautery. Sterilized
dressing material, splints, firstaid, haversack, blankets and clothing for the injured and
emergency medicines are also provided. Facility for autoclaving, and sterilization, oxygen
supply, artificial respiration equipment and resuscitation kit are also provided (Medical
equipment list at Annexure D).
1.2.2.7 Supervisor Van will have berths for rescue team. It should also carry adequate supply of
drinking water and provision for tea, coffee and light refreshment to be served to affected
passengers for which a kitchen is provided in SPART.
1.2.2.8 SPART shall be readily available at all times on a stabling siding set apart exclusively for this
purpose, preferably with double exit.
1.2.2.9 With a view to test the readiness and quick turn out of SPART, it is required to have
periodical drills once in every quarter. SPART will proceed upto the mock accident site.
1.2.3 Accidents Covered
1.2.3.1 SPART will be sent for rescue operation for consequential train accidents. On IR system,
consequential train accidents include train accidents having serious repercussion in terms
of loss of human life, human injury, loss to railway property or interruption to rail traffic.
Train accidents under following classifications will be termed as consequential train
accidents:
a) Collisions: This refers to the impact of a train against another train or vehicle. It includes
headon collision, rear collision and side collision.
b) Fire in Trains: A fire in a train should be treated as a train accident only when it results
in death or physical injury or loss (damage) of railway property with a value of Rs.
50,000 and above.
c) Accidents at Level Crossings: This refers to a train running into road traffic, and / or
road traffic running into trains at level crossings. Level crossing is the intersection of the
road with railway track at the same level.
d) Derailments: This refers to the offloading of wheel or wheels from the track causing
detention or damage to rolling stock / permanent way.
1.3 Vehicle Configuration
14
1.3.1 SPART shall be a Diesel Electric Multiple Unit, with speed potential of160 kmph, on Indian
