The public is invited to a meeting Oct. 21 to discuss the future of IndyGo’s north-suburban commuter routes, which are in danger of being discontinued.

The meeting is at the Fishers train station, 11601 Municipal Drive, at 7 p.m.

The luxury coach routes from downtown to Fishers and Carmel were launched three years ago and have been popular among suburban commuters. There were more than 81,000 passenger trips on the Fishers route and 54,000 on the Carmel route last year.

But the heavily subsidized service at year-end will have expended its biggest source of funding, a federal Congestion Mitigation and Air Quality grant. Although Fishers and Carmel were to pick up the other 20 percent, fairbox revenue has been strong enough to avoid local government match.

The Central Indiana Regional Transportation Authority has been looking for money to replace the expiring federal grant but so far, at least, hasn’t the cash.
