Oh god, here we go again.
A TUNNEL IS ALWAYS SUPPOSED TO HAVE SEEPAGE OR LEAKAGE.
It is not a bug, it is by design. And this is called controlled leakage in areas that are wet or receive heavy rainfall.
Rain/water falls, gets soaked by the soil or seeps down into the weathered rock cracks naturally. Once it reaches the tunnel lining, it starts accumulating like an underground reservoir of sorts because it has nowhere to go. Once there is enough volume, it'll start exerting hydro-static pressure on the walls and ceiling. If left as is, it'll crack or even literally blast open the lining and we'll have a tunnel cave-in.
Never ever ever fuck around and underestimate the power of water.
To prevent this from happening, controlled seepage is implemented where water is by design given space or outings to drop out and relieve pressure.
The seepage water is then by-design collected in the drains that are present on both the sides to ensure there's no water logging or flooding.
Look at the picture below. Both the sides have a drain with openings at very frequent intervals. Water is accumulated and pumped out artificially or via gravity.
None of the tunnels you see in these regions will be leakage-free. None.
Water drips or falls even in the older tunnels of Mumbai Pune Expressway (Bhatan/Kamshet/Adoshi). Konkan Railway or Freeway tunnels let water pass.
Even Mumbai Metro 3 tunnels are not technically "water proof", they too have seepage. What matters is whether we're able to drain out the water.
Such tunnels need periodic check-ups to ensure the dripping water isn't a structural issue as such, or whether the so-called "cracks" are on the paint/upper surface or the actual thick concrete lining.
China manufactures
89% of the world’s solar panels, 70% of the world’s wind turbines, 83% of the world’s batteries, and 75% of the world’s electric vehicles among other things
The problem. No concept of ROE
From 2021 to 2025, Chinese corporate profits CAGR -3.99%.
Industrial profits contracted from 8.71 trillion yuan in 2021 to 7.40 trillion yuan i.e. around 16-17% decline over 5 years.
ROE of corporate sector ~7-8%
ROE in India 16-17%
ROE Avg S&P 500 15-16%
It's very important to prevent backdoor entry of state subsidized Chinese Corporates into India.
Saving 1.2L crore in forex helps reduce Rs depreciation which saves money on all imports including fuel. The benefit of lower inflation is passed onto all consumers, while money farmers earn is spent in India increasing GDP and wealth levels.

@arulmuru182002 Boomer uncle really thinks platform screen doors can be installed at railway stations as easily as in the metro. Is your father doing PF door cleaning services or what?
@arulmuru182002 Indian Railways already planning access controlled entry points, but i can't help sugar patients who cant comprehend to think it will take years to implement across entire Indian railway platforms.

Biggest morons are the ones picking up 2 or 3 potholes in a 1000 km highway and cribbing about it ..
Your life have become 1000 times safer on roads than what was 12 years ago ..
