A very good step which should have been taken decades back.
(1) Minimise the deaths happening in Mumbai Suburban cestion due to tresspassing.
(2) Further encroachments shall be curbed and the wall shall make a better environment when there is need to evict the encroachers for laying additional lines in future.
(3) Ensure safetu of travelling paxs, as the wall shall prevent incidences...
more... of stone throwing by urchins on the running trains often leading to grave injuries to travelling paxs.
However, some precaution/ cre is needed by way of:
(1) Intense Surveillance required for at least a few months after construction of walls, so that people do not break walls at places they intend to cross
(2) But the trespassers (large in numbers) shall now compulsorily use overbrigdes, which may need to be augmented.
