4.23 Brief Description of Signalling & Telecom assets in the Wadi (Excluding) –
Vikarabad – Lingampalli – Bidar section:
4.23.1 The section is having all Panel Interlocked stations with IBS and mid Block
Section Level Crossing Gates as shown in the table. The section from
Lingampalli to Wadi (Excluding) is double line Electrified section with
Double Line Lock and Block Instruments. Block Proving / IBS Axle
Counter is presently provided in Lingmapalli – Vikarabad – Tandur section.
The section from Vikarabad to Bidar is Single Line Non-electrified section
with podanur type push button block instruments.
4.23.2 All the stations are Central Panel interlocked stations except for Vikarabad.
Vikarabad Station is having two end-panels and one panel for the purpose
of slotting at Central Location. However, the status of all signal aspects,
Track circuits, points, block section occupation is covered by both the endpanel
locations. Status of all the signal aspects of Level Crossing Gate no. 3
(mid- block section interlocked Level Crossing Gate between Sadashivpet
Road and Vikarabad) are covered by Vikarabad and Level Crossing Gate
no. 4 (mid- block section interlocked Level Crossing Gate between
Sadashivpet Road and Vikarabad) in such a way that they are available at
either of Vikarabad and Level Crossing Gate no. 4. Therefore, separate
stationary TCAS unit is not required at Level Crossing Gate no. 3.
Similarly, Status of all the signal aspects of Level Crossing Gate no. 43
(mid- block section interlocked Level Crossing Gate between Matalkunta
and Bidar) are covered by Bidar and Level Crossing Gate no. 42 (midblock
section interlocked Level Crossing Gate between Sadashivpet Road
