Tender invited for Development of Train Collision Avoidance System

SN Description
(x) Handling of RF Reception of transmission generated from four
simulated stationary TCAS Units by four simulated Locomotive
Units (Simulation may be exclusively for the purpose of
demonstration of TDMA concept only which may even be
without using or involving full-fledged lab models).
5 Capability to demonstrate following functions in Field Trial
(Based on report if already done with RDSO)
(i) Display of Red, Green, Yellow, Double Yellow Signal Aspects in
Loco Cab, Distance to next Signal at Red (Stop / Danger Aspect)
at same interlocking in Loco Cab
(ii) Application of brakes to a train approaching too fast to a signal at
Red and release of brakes by TCAS when the Movement
Authority is increased by taking off a signal which was earlier at
Red.
(iii) Assessment of braking characteristics of train through Brake Test
and its application while calculating braking distance
(iv) Application of brakes by TCAS to prevent Head-on collision and
rear-end collision between trains on same track not otherwise
prevented to be so on same track.

(v) Application of brakes on reception of “Unusual Stoppage
message” or SOS message from other train in vicinity while
approaching it.

3.5.6 Based on technical evaluation, the firms shall be divided in two categories
based on marks obtained as under. The marks and category of Technical
Evaluation shall be uploaded on Website:
(a) Category I if marks obtained are 60 or more
(b) Category II if marks obtained are 45 or more but less than 60.
3.5.7 If there are three or more firms in category I, firms in category I only shall
qualify for next stage of bid evaluation otherwise all firms in category I and
II shall qualify for next stage of evaluation.
3.5.8 The marking pattern is such that the tenderers get either zero or full marks
against any sub-item and it shall not be divided further to the fraction of the
indicated Maximum Marks for that sub-item.
