*****STATEMENT REFERRED TO IN REPLY TO PARTS (a) TO (f) OF LOK SABHA
STARRED QUESTION NO. 255 TO BE ANSWERED ON 17.12.2025
(a) to (f) : Sanctioning of works of Road over Bridge (ROB)/Road under
Bridge (RUB) in lieu of Level crossings (LCs) is a continuous and dynamic
process of Indian Railway. Such works are prioritised and taken up on the
basis of its impact on safety in train operations, mobility of trains &
impact for road users and feasibility etc.
Nos. of ROBs/ RUBs constructed on Indian Railways during the
period 2004-14 vis a vis 2014-25 (Oct’25) is as under:
Period ROBs/ RUBs constructed
2004-14 4,148 Nos.
2014-25 (Oct’25) 13,653 Nos.
As on 01.11.2025, 4689 Nos. ROBs/ RUBs are sanctioned at the cost
of ₹1,11,583 Cr on Indian Railways including 316 Nos. Road Over Bridge
(ROB)/Road Under Bridge (RUB) at a cost of ₹ 11,686 crore in the State of
Andhra Pradesh, which are at various stages of planning and execution.
06 Nos. ROBs/RUBs works are sanctioned at a cost of ₹ 208 crore in
Tirupati Lok Sabha Constituency.
43 Nos. RUBs exist in Tirupati Lok Sabha Constituency. During
heavy rains, problem of water logging has been reported for short
duration during last monsoon season in three RUBs (RUB Nos. 85A at Km
63/100-200, 90A at km 64/300-400 and 95A at km 69/900-70/0 on Gudur
Junction-Renigunta junction section), which are addressed promptly by
provision of heavy duty pumping arrangement. Further, stationary
watchman, warning signs and gate barriers have been provided.
Railways are working with municipal bodies and other local bodies
for integrated drainage solutions at subway locations. Further, Railwayshave taken several remedial measures to mitigate the problem of water
logging in subways as under:
(i) Adequate drainage arrangement is made as integral part of planning
of new Road Under Bridge (RUB)/Subways.
(ii) In existing RUBs/subways remedial measures like water flow
diversion to nearby bridge and nallahs/drains, provision of cover
shed on approach roads, provision of hump at entry to Road under
Bridge (RUB), provision of cross drains, sealing of joints etc. are
made as per feasibility, suitability and site requirements.
(iii) Pumping arrangement is also been made for identified RUBs, to
drain out water expeditiously in case of emergency and provision to
stop road traffic in exceptional/unusual rainfall situation for safety
of road users.
Based on detailed survey of RUB/Subways, as on 01.04.2025, 2670
locations were identified by zonal railways prone to water logging out of
total 14,745 RUB/Subways already constructed. Railways have taken up
the work of permanent remedial measures on these RUB/Subways and
with consistent efforts, 1351 RUBs/Subways have been provided with
necessary infrastructure to prevent water logging and maintain its
functionality in future. Balance RUB/Subways have also been provided by
temporary solution i.e. dewatering arrangements. Moreover round the
clock manning of vulnerable RUBs where there is possibility of flooding
are also being done by deputing RUB Mitra/Stationery Railway Watchman.
The objective of all this exercise is to keep RUBs/Subways functional
throughout the year.
