The railway budget presented this week has given broad hints that Mumbai may get partial air-conditioned local trains instead of the full ones that have been plying amid low response. The Assets-Acquisition, Construction and Replacement for 2021-22 Railway Board budget document opened a new head for ‘Partial Air Conditioning of 78 EMU rakes for running in Mumbai at a cost of Rs 507 crore’. A sum of Rs 1,000 crore has been allocated this year, opening a new accounts head.
