On Indian Railways, new high speed lines are being laid to cater for demand of increasing traffic density. In various Zonal Railways high speed turnouts with thick web switches are being installed.
Salient features of TWS
The switch opening is of 160 mm as against of 115 mm of ordinary cross over.
The crossing angle has been broadened so that the train negotiating at higher speeds does not pose any danger.
The web of the switches is made thicker to make than them strong enough to withstand load of train at high speeds.
Thick Web Switches
Spring setting device (SSD)
In a TWS turnout, no stretcher bar is used and hence switches are able to move independently.
A spring setting device (SSD) is provided at junction of Rail head (JOH), in lieu of stretcher bars, to assist in proper setting of switch upto JOH, which is placed between sleeper number 13 and 14.
Adjustment of locking is done by means of packing shims between switch rail and stock rail bracket. Three each of 1 mm and one of 0.5 mm shims are provided for each switch.
Joint Inspection of Points & Crossings (Thick-Web Switches)
Recently, some of the railways have raised certain issues related to maintenance of Thick Web Switch (TWS) turnouts and Track circuit insulation problems which involved issues pertaining to Track maintenance as well as signalling.
The final proforma for Joint Inspection of Points & Crossings of Thick Web Switches incorporating the suggestions by Track & Signal Directorates of RDSO is enclosed herewith. Download the Proforma.

Signalling System enhances safety in train operations. Upgradation and replacement of equipments in use over Indian Railways is a continuous process and is undertaken based on its condition, operational needs and availability of resources.
Major steps taken for Modernisation of Railway Signalling Systems
In order to further improve safety in train operation and generate additional line capacity, modernisation of Signalling System has been taken in hand. Following major steps have been taken,
6084 (96% of total Stations) Stations on Indian Railway have been equipped with modern Electrical/Electronic Signalling Interlocking System up to 29.02.2020.
Electronic Interlocking are being adopted on a large scale to derive benefits of digital technologies in train operation and to enhance safety. So far 1913 stations have been provided with Electronic Interlocking upto 29.02.2020.
Axle Counters for Automatic clearance of Block Section (BPAC) are provided to ensure complete arrival of train without manual intervention before granting line clear to receive next train and to reduce human element. These systems have been provided on 5661 block sections upto 29.02.2020.
In order to increase line capacity to run more trains on existing High Density Routes of Indian Railways, Automatic Block Signalling is a cost effective solution. As on 29.02.2020, Automatic Block Signalling has been provided on 3207 Route km.
Enhancing Safety at Level Crossing Gates has been a major area of concern. Safety gets enhanced by interlocking level crossings with Signals. Indian Railways have provided interlocking with Signals at 11622 Level Crossing Gates to enhance the safety at Level Crossings as on 29.02.2020.
Modernisation of Signalling System is proposed to be taken up on High Density Routes of Indian Railways including Golden Quadrilateral (GQ) and Golden Diagonal (GD) Route. The work includes provision of Modern Train Control System.
As a prelude to modernisation work of signalling system on Indian Railways, four works totaling 640 Route km at total cost of ₹ 1,609 crores have been sanctioned in Supplementary Works Programme 2018-19 in following sections for extensive trials,
Tenders for the works have since been opened and are under evaluation.
Two works of Raising of speed to 160kmph on existing New Delhi – Howrah and New Delhi – Mumbai routes have been sanctioned including modernisation of Signalling and detailed estimates are under preparation.
An indigenous Automatic Train Protection (ATP) System namely Train Collision Avoidance System (TCAS), has been developed by Indian Railways in association with Indian manufacturers. The system has been installed on Lingampalli – Vikarabad – Wadi & Vikarabad – Bidar section (250 Route km) of South Central Railway.

Entire GQ-GD route over South Central Railway, now fit to run at 130 Kmph Speed
A total of 2824 Kms (including Up &Down Lines) over South Central Railway Zone is now fit to run at 130 Kmph speed.
Indian Railway has started the New Year 2021 by achieving a landmark achievement by drastically enhancing the maximum speed to 130 kmph for 1,280 km length out of 1,612 Km in Golden Quadrilateral – Golden Diagonal (GQ-GD) route.
This covers the entire GQ-GD route over South Central Railway, except Vijayawada – Duvvada section, where signalling up-gradation work is in progress.
The enhanced speed limits could be achieved due to the systematic and planned strengthening of track & its infrastructure by removing bottlenecks in these sections on a fast pace. This included heavier rails, laying of 260 meters Long welded rail panels, improvement of curves and gradients among others.
Based on these improvements done by the Zone, the RDSO/Lucknow conducted oscillation trials through Confirmatory Oscillograph Car Run (COCR) consisting of instrumented coaches of all classes at 130 Kmph speed during July and October last year. During this check, in addition to track parameters, other areas like Signalling aspect, Traction distribution equipment, Locomotive& coach fitness were also checked and recorded.
Accordingly, the South Central Railway zone has received sanction to enhance the maximum speed limits to 130 kmph along the following routes:
1. Golden Diagonal (Grand Trunk) Route: 744 Route Km
i. Ballarshah to Kazipet – 234 Rkm
ii. Kazipet-Vijayawada-Gudur – 510 Rkm
2. Golden Quadrilateral Route (Chennai -Mumbai section): 536 Route Km
i. Renigunta to Gooty – 281 Rkm
ii. Gooty to Wadi – 255Rkm
Already, the maximum speed limits in the High-Density Network (HDN) between Secunderabad – Kazipet (132 Kms distance) had been enhanced to 130 kmph. Source: PIB
As such, including both the Up and Down lines in these sections, a total of 2,824 kms (1412Rkms) has now been made fit to run at a speed of 130 kmph. This covers the entire GQ-GD route over SCR, except Vijayawada – Duvvada section, where signaling up-gradation work is in progress.
It is noteworthy that despite COVID pandemic, Indian Railways has witnessed an unprecedented growth in development of infrastructure, innovation, capacity expansion of network, freight diversification. Railways has used covid challenge as an opportunity to lay the foundation for future development and next level of traveling experience for passengers.

In Electronic Interlocking (EI) system, provision exists that whenever system (A) goes in error state or fails, the EI works on another system (B), but no information is relayed to concerned maintenance staff about this incidence.
In this regard, Ajmer division of NW Railway has developed a SMS generation and exception reports system for above type of EI incidences by using system (A) and system (B) healths bits with the help of fault logic of data logger. Whenever any system of EI fails, exception is generated in data logger and SMS is sent to concerned staff and officers which serves as remote monitoring of EI health & preventive action. This is provided at EI system, Westrace make at Falna station on Ajmer – Palanpur section of Ajmer division as a pilot.
This innovation shall be useful in addition to above for the cases where one system is in faulty condition and the maintenance staff is not aware of the same. Any attempt for changeover to stand-by system either due to fault or as a routine maintenance may lead to catastrophic condition.
Failure of EI of Ansaldo system…
In Ansaldo make EI systems, Vital Cut-Off Relay (VCOR) is used for monitoring the health of the EI system. For system (A), A1-VCOR, A2-VCOR, A3-VCOR… and for System (B), B1-VCOR, B2-VCOR, B3-VCOR… relays are used as per the requirement of the yard. For normal 3-Line station, System (A) consists A1-VCOR, A2-VCOR & System (B) consists B1-VCOR, B2-VCOR relays are required. These relays are normally remain in Pick-up condition.
When any of the system fails and remains fail for more than 2 minutes, respective VCOR relays drops and that signals the failure of that particular system. For stand-by systems also this relay remains in normal pick-up condition. Thus, monitoring these relays in parallel and timer of more than 2 minutes can be used for SMS generation on failure of EI system.
On failure of a safety-critical diagnostic, the DC supply to the VCOR is removed thereby opening the contacts that provide battery power to the vital output boards.
Vital cut off Relay (VCOR)
This feature of SMS generation on failure of EI should be used for all types of EI…
Do you know, how can we implement this on Medha EI system and Kyosan EI systems???
