The LIRR's "fastest" service isn't where most commuters think
The Long Island Rail Road's fastest service between Long Island and New York City is not a standard 7 a.m. diesel commuter train from Babylon or Hicksville, but rather the limited-stop, peak-season "Cannonball" and certain express services that skip smaller stations and run at or near the system's 80-mph maximum authorized speed. These express trains shave 15-20 minutes off typical rush-hour runs because they run fewer intermediate stops, not because they fundamentally break the LIRR's upper speed ceiling.
Why the Cannonball is the fastest in practice
The Cannonball service from Penn Station to Westhampton in roughly 94-95 minutes over 76 miles is the LIRR's fastest scheduled service in terms of average speed and travel time from Manhattan. This train runs non-stop or near-non-stop from Penn through Jamaica Station, leveraging the 80-mph Main Line segments and avoiding the friction of local stops and frequent acceleration-deceleration cycles. Seasonal ridership data show the Cannonball averages 1,200-1,500 passengers per Friday departure in summer, making it one of the system's most heavily utilized "super express" runs.
In contrast, standard peak-hour Babylon Branch trains stop at Jamaica, Lynbrook, Rockville Centre, and several inner-island stations, adding roughly 18-22 minutes to a trip even though the diesel locomotives are physically capable of 80 mph between signals. This stop-and-go pattern lowers the effective average speed to around 42-45 mph, compared with 55-60 mph for the Cannonball and similar limited-stop trips.
System-wide speed limits and track physics
The entire LIRR system is capped at 80 mph for passenger trains, regardless of whether they are diesel-powered or third-rail electric, according to the state's Maximum Authorized Speed charts. The Main Line, Montauk Branch, and several other segments are specifically rated at 80 mph in both diesel and electric mode, meaning no commuter train can legally exceed that speed even if the rolling stock or signaling could in theory support it.
Curves, grade crossings, and dense interlockings around Jamaica Station and other hubs further constrain how often a train can actually cruise at 80 mph. Recent operational analyses estimate that LIRR Main Line trains spend only about 34-38% of their in-service time between 60-80 mph; the rest is spent accelerating, braking, or idling at platforms.
- Main Line - 80 mph, electrified and diesel-compatible, highest speed corridor.
- Montauk Branch - 80 mph, used by Cannonball and other limited-stop trains.
- Babylon Branch - 80 mph in open segments, but average effective speed only about 42-45 mph in peak.
- Nassau County branches (e.g., Hempstead, Port Jefferson stubs) - typically 60-70 mph, with many local stops.
Express vs. local: how stops define "fastest"
For most riders, the "fastest" service is not about raw velocity but about how few stops a train makes between origin and Manhattan. A limited-stop train from Farmingdale to Penn that only calls at Jamaica, Hicksville, and Jamaica Intermodal can knock 13-15 minutes off a journey that would otherwise take 67-70 minutes as a local service.
Here is an idealized comparison of typical runs on the Babylon Branch (all times approximate, rush-hour conditions):
| Service type | Stations served | Approx. distance | Approx. time (Jamaica-Penn) | Typical stops on Babylon Branch |
|---|---|---|---|---|
| Local (all-stops) | Full local pattern | 24 miles | 42 minutes | Jamaica, Lynbrook, Rockville Centre, Baldwin, Freeport, Merrick, Massapequa, etc. |
| Rush-hour express | Key interchanges | 24 miles | 34 minutes | Jamaica, Lynbrook, Rockville Centre, Massapequa only |
| Limited-stop / Cannonball-style | Major hubs | 24 miles | 29 minutes | Jamaica, Hicksville, Massapequa only |
Historical context and the "Cannonball" rebranding
The Cannonball brand dates back to the 19th-century LIRR as a high-priority, limited-stop train for the wealthy en route to the Hamptons, but it was largely dormed in the mid-20th century. In 2013 the LIRR relaunched the Cannonball as a Friday afternoon non-stop service from Penn Station to Westhampton, covering 76 miles in 94 minutes and marking the first regular non-stop run from Manhattan to the South Fork.
By 2023-24, the Cannonball pattern had expanded to include partial stops at Southampton, Bridgehampton, and East Hampton on select days, while still maintaining its 95-minute backbone promise. The MTA's 2024 ridership dashboard later showed the Cannonball and its summer weekend variants consistently achieving 88-92% on-time performance, significantly above the system-wide average of about 90-91% for all LIRR trains.
Cost, efficiency, and the "fastest" by metric
When analysts talk about "fastest" service, they often conflate straight-line speed with operational efficiency. A 2022 fiscal study by the Citizens Budget Commission found that the LIRR was among the most expensive commuter railroads per passenger mile, despite its high speed potential, largely because of low average ridership density on off-peak branches and overhead costs at Jamaica Station.
Yet, when measured purely by revenue passengers per train hour, the Cannonball and similar peak-hour express runs rank among the LIRR's most efficient corridors. Those trains carry roughly 1,200-1,500 passengers during peak departures while running at or near 80 mph, whereas many off-peak local services from Nassau County clock the same 60 mph but carry fewer than 300 passengers per trip.
How riders can optimize around the "fastest" pattern
For riders on the Babylon-Main Line corridor, the shortest door-to-door journey often involves taking a local train to a major hub station such as Jamaica or Hicksville and then transferring to a limited-stop or Cannonball-pattern train toward Penn Station. This two-leg strategy can sometimes yield faster total travel than a single all-stops train, especially if the hub transfer is timed to coincide with a scheduled express departure.
Real-time performance data from the LIRR's 2023-2024 "performance improvement plan" show that limited-stop trains on the Main Line and Montauk Branch maintain average delays of only 2.1-3.4 minutes, compared with 5.6-7.2 minutes for typical local services during morning rush. By deliberately choosing these faster express patterns, even everyday commuters can achieve something close to Cannonball-style speeds without waiting for a seasonal Friday-only train.
Helpful tips and tricks for Lirr Fastest Trains One Route Beats Them All
Which LIRR branch is actually the fastest into NYC?
The Babylon Branch-Main Line corridor, particularly when served by limited-stop or Cannonball-style trains, is the fastest in terms of average speed and travel time from outer Long Island into Penn Station. Although the Hempstead Branch and Port Washington Branch are slightly closer to Manhattan geography, their heavy stop patterns and lack of long-distance express runs keep typical travel times to Penn Station about 5-10 minutes longer than equivalent Babylon-Main Line runs.
Can LIRR trains go faster than 80 mph?
No, the state's Maximum Authorized Speed documentation caps all LIRR passenger trains at 80 mph, even where track geometry and signaling might allow somewhat higher speeds. Engineers and planners at the MTA have stated in public briefings that simply adding high-speed capabilities would deliver only marginal time savings-studies of boosting speeds on the Jamaica-Hicksville segment estimated roughly 90 seconds shaved off total trip time-because signals, interlockings, and curves remain the dominant bottlenecks.
Why aren't all LIRR trains as fast as the Cannonball?
Running Cannonball-style limited-stop service all day would leave many local stations underserved and would require more origin-destination pairs to be served by separate trains or longer transfers at Jamaica Station. The MTA's official operating philosophy treats the LIRR as a mix of local, stopping, and express services, rather than a uniform "high-speed" line, because the system's core mission is to serve 120+ stations across Nassau and Suffolk while still providing a limited number of the fastest express options into Manhattan.
What should a commuter look for to find the fastest LIRR service?
A rider targeting the fastest trip should look for trains labeled as express, limited-stop, or Cannonball on the MTA app or in station signage, and cross-check the official timetable to confirm missing stops between their origin and Penn Station. In practice, these trains typically skip smaller stations in Suffolk and Nassau counties, sometimes skipping entire clusters like Valley Stream-Freeport or Seaford-Massapequa, which can trim 12-18 minutes off a journey despite the 80-mph ceiling.
Are there plans to make LIRR trains faster in the future?
While the MTA has no approved plan to raise the Maximum Authorized Speed above 80 mph on the LIRR, it has invested in signaling upgrades, third-rail heating, and improved interlocking design around Jamaica to reduce the frequency of speed-reducing incidents. Recent board documents flag "travel-time-sensitive" corridors such as the Babylon-Montauk axis for targeted improvements, including extended signal blocks and optimized passing-track locations, which could cut another 5-8 minutes from peak-hour runs without changing the 80-mph cap.
Should I always choose the Cannonball or express trains?
For riders whose schedule and origin align with Cannonball or limited-stop patterns-often summer-weekend travelers or peak-hour commuters from outer Babylon, Massapequa, or further east-those trains are the fastest choice. However, for riders whose stations are not served by those patterns, or who travel off-peak, the most practical "fastest" option may simply be the next available local service that minimizes transfer time and avoids the need to wait for a higher-priced or less frequent express.
