Western Railways today announced a major block of all trains that depart from Mumbai. 
Trains will be blocked to launch and then de-launch an existing girder of North span of Bridge no. 92 lying between Saphale and Vitarna. 
This mega block of trains will span for 10 hours and 15 minutes. The bridge falls on the Up line between Saphale and Vitarna stations. 
Local trains plying between Virar and Dahanu stations will be suspended, but some effects will be felt for all trains departing from Mumbai.
During this block period 14 locals, 9 MEMU and 5 Passenger trains will remain cancelled. 
The good news for long distance travellers from Mumbai is that no long distance trains are cancelled; they will be regulated to accommodate the construction work.
