EOI Invited to Supply 50 Coaches for Nashik Metro Neo
Maharashtra Metro Rail Corporation Limited (Maha Metro) earlier this week invited Expression of Interest (EOI) applications from electric trolley bus manufacturers to supply 50 coaches for the 32 km Nashik Metro Neo project.
Metro Neo is a low-cost electric trolleybus-based transit system aimed to built in cities with a population of less than 10 lakh (tier-3) and suburbs of bigger cities. Rubber-tyred articulated electric buses will run by drawing power from an overhead electrical (OHE) system.
- Date of Pre-EOI Meeting: 20.04.2021 at 11:00 Hrs
- Submission Deadline: 05.05.2021 at 16.00 Hrs
- Date & Time of Opening of EOIs: 05.05.2021
Tender Notice: NS1-RS-02/2021
Scope: Expression of Interest for Design, Manufacture, Supply, Testing, Commissioning of Tyre Based Electric Bus Running on OHE at Nashik for Maharashtra Metro Rail Corporation Ltd.
MahaMetro wants the coaches to be of modern design, lightweight, be made of stainless steel / aluminium with regenerative braking, and operate on 750V DC flexible Overhead Catenary System (OCS).
They also require minimum 75% of the coaches to be manufactured indigenously per MoHUA’s directives to promote the ‘Make in India’ or AatmaNirbharBharat campaign.
Nashik Metro Neo’s Detailed Project Report (DPR) with 2 corridors was prepared by RITES and approved by Maharashtra’s cabinet in August 2019. MahaMetro is looking to operate 36 coaches on Line-1 and 14 coaches on Line-2.
- Line-1: Gangapur – Nashik Road Railway Station (22 km, 20 stations)
- Line-2: Gangapur – Mumbai Naka (10 km, 10 stations)
On Wednesday, the Ministry of Finance’s Public Investment Board (PIB) had recommended this Rs. 2100 crore project for approval by the Central Government’s cabinet.

Here’s MahaMetro’s concept video from 2019:
I’m not sure why they’d have different but awfully close length specifications for both lines’ coaches. To optimize manufacturing costs, ideally there should be one specification.
Anyhow, this EOI process is just a “feeler” to see which vendors out there would be interested and capable of bidding for the coaches. When it concludes, MahaMetro will invite bids from the shortlisted firms. I’m curious to see who submits applications!
