Escalator install on Andheri station platform no.4 & 5 is shut for maintenance from last 20 days, i am not able to understand if the escalator install on other platform of Andheri station are working smoothly then what is wrong the escalator of platform no. 4 & 5 and also doubt the competency of engineers as repairing the same takes such a long time. Also the sheds of railway platform has lot of garbage which can be viewed from overbridge. Also at the start of platform no. 8 and 9 of Andheri station people relieve themselves, urgent attention required by rail authority.
