The feeder shuttle that carries riders between Metro-North's Spuyten Duyvil and Riverdale stations and the neighborhoods above them has operated on weekdays only since its 1991 launch — leaving weekend Hudson Line passengers to navigate the climb on their own.

The Hudson Rail Link runs eight routes, accepts OMNY, carried 204,608 riders in 2024 — and shuts down entirely every Saturday and Sunday.

The Rail Link is a Metro-North–contracted feeder bus, operated by Arrow Rail Link Service (Consolidated Bus Transit), that connects Spuyten Duyvil and Riverdale stations on the Hudson Line to the residential hills of northwest Bronx. Four routes (A, B, C, D) serve Riverdale station at the foot of West 254th Street; four more (J, K, L, M) serve Spuyten Duyvil, off Edsall Avenue. Since the service launched in 1991, it has run on weekdays only, timed to Metro-North train arrivals and departures. Route M — the newest — was added in 2002. The service has never been extended to weekends.

Metro-North's Hudson Line runs seven days a week. So does the geography: the Riverdale neighborhood rises sharply above both stations, and by 2014, more than half of daily Spuyten Duyvil commuters were reaching their platform via the shuttle, according to a report cited by the Riverdale Press. On weekends, those riders — and anyone else arriving at either station — are on their own.

The 204,608 annual riders logged in the MTA's 2024 ridership report works out to roughly 787 per weekday, compressed entirely into the five-day service window. Metro-North sets the operating contract; any expansion to weekend service would require MTA and Metro-North Railroad approval and a contract amendment with the current operator. No such proposal has been announced.

The Rail Link is the smallest piece of the Metro-North network, but for residents between the train platform and the top of the hill, it is the trip. Right now, that trip exists only Monday through Friday.
