## 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, Railways have 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.
