Upcoming Release Northeast Corridor Metro-north - Gameplay Deep Dive & Release Tomorrow!

Following on from our overview article, which gave an insight into the complex Metro-North and Amtrak trackage that makes up the bustling Northeast Corridor between New York and Stamford, it’s time for a deeper look at all the gameplay you can look forward to. Firstly, we wanted to apologise for the release date communication.

At the start of this week we postponed our NEC New York – Stamford preview, as well as holding on announcing the original release date, whilst our teams worked to resolve an in-game issue impacting the M8 braking. That issue is now fully resolved and so we’re on track with our original planned release date of Thursday March 19th 2026 – which is tomorrow!

Unfortunately, due to the extra time needed to test and confirm the M8 braking issue, our teams have not been able to finalise setting up the game builds for our Medway Valley preview this evening. Whilst the route and content are completely ready for release, we're sorry to say that we will have to delay the preview livestream until next week, which will now take place on Wednesday 25th March 2026. We can’t wait to join the Firefly Simulations team to show you all an exclusive look at everything they have prepared, so be sure to join us then!

We apologise that the timeline has worked out this way and that the communication has come so suddenly for the release of NEC New York – Stamford, but we wanted to ensure that the add-on was in a good shape ahead of confirming the date. We will be live on our Train Sim World YouTube channel tomorrow night to give the route a full showcase, so you still have a chance to see the route live in action, and our creators will also be sharing content they’ve made from tomorrow, so be sure to check these out!
For now, let’s turn our attention to Tyler of Rivet Games who reveals all there is to know about Big Apple operations.

The Timetable
Buckle up for the most intensive US timetable to date!

The 24-hour timetable includes almost 600 playable services with all layers, including frenzied rush hours at Grand Central Terminal, special trains for baseball and football games, and over 18 hours of freight gameplay including switching and locals that serve customers along nearly the entire route.
While the route is set in 2015, we are using detailed information from January 2020, including formation diagrams, consist lengths and platform allocations for our timetable.

The route comes with three trains: the Metro-North M8, the Amtrak® ACS-64 with Amfleet coaches, and the CSX SD40-2. The 89-foot flatcar with trash containers is included, and we've moved additional freight cars to core so you don't need any additional add-ons for freight gameplay; freight cars used on the route include a two-bay aggregate hopper, a covered hopper, a boxcar, a tank car, and a centerbeam flatcar.
A number of other trains will layer into the timetable if you own them, described below.

Commuter Connections with the M8


The M8 has a total of 309 playable services with a variety of service patterns, including trains which run express between New York and Stamford to continue off-route to New Haven, locals to Stamford, rush-hour short-turns between Grand Central and New Rochelle or Harrison, and deadheads from everywhere to everywhere!

Between runs, some M8s head to yards to await their next assignment. You'll start and end many runs at Stamford Yard, following its unique yellow-and-white switch position signals to the storage tracks alongside the main line. A spur at New Rochelle is used to turn some rush-hour trains. You'll also take M8s as far as Yankees-E 153rd Street on their way to midday storage at Highbridge Yard. Please note that the many yard tracks at Grand Central Terminal are not used in service mode for performance reasons, and instead trains are sent into hidden portals to free up memory and increase your frame rate. Such is the cost of modeling both levels of the world's largest train station (by number of platforms).

Revisiting the Hell Gate Line with the ACS-64


The Amtrak ACS-64 handles intercity trains between Penn Station and Stamford, over the monumental Hell Gate Bridge. Longtime TSW players may get flashbacks to the old NEC New York route. While parts of this route are based on Morristown and the Harlem Line, very little of the old NEC route survive - mostly bridge assets. The rest, including scenery and track, were recreated from scratch.

Most ACS-64 services north of New York are Northeast Regional services to Springfield or Boston, Massachusetts, but you'll also work the Vermonter with its shorter consist and cafe car at the rear. In total, the ACS-64 provides a total of 25 playable services. If you own Horseshoe Curve, you'll also gain an early-morning work train and an afternoon light engine move.



Amtrak’s Acela® is also layered in, providing 21 playable services.

Penn Station hosts representative AI services designed to make the station feel alive without compromising performance. This prioritizes Long Island Rail Road M3 and M7 traffic, since you'll see it near Sunnyside Yard, and includes a limited amount of NJ TRANSIT® services with the ALP-45, ALP-46 and Multilevel coaches, some of which are playable between Penn Station and Sunnyside Yard. Amtrak services from the south which terminate at Penn Station or Sunnyside Yard are not modeled.



Switching with the SD40-2, all the livelong day


You can stay busy all day with the CSX SD40-2 and the freight deliveries to be made around Oak Point Yard in the Bronx. The day starts with the arrival of the road freights from Selkirk. The mixed freight needs to be sorted by destination: refrigerated boxcars of produce, covered hoppers of flour, boxcars of beverages, boxcars of newsprint, and assorted freight cars headed over the Hell Gate Bridge for interchange in Long Island. Meanwhile, flatcars of empty garbage containers need to be swapped for their loaded counterparts. Taking out the trash is a heavy-duty job in the Big Apple!

The afternoon is spent serving customers, including a lengthy trip to Hunts Point Market to deliver produce and flour. You'll also switch a beverage warehouse and bring newsprint to the printer for tomorrow's paper, or maybe take the interchange cars to Long Island (playable as far as the far end of the Hell Gate Bridge). When all is done, someone has to build the outbound train.

As darkness falls, your work continues, because nighttime is when you can access the main line without delaying passenger trains. There's a lumberyard east of Stamford that needs a delivery (playable as far as Stamford), and on the way back you'll deliver plastic pellets to a factory in Mamaroneck and building materials to a lumberyard in the Bronx. By the time you hand the train over to an AI at Yankees-E 153rd Street, you'll be able to say you worked on the railroad all the livelong day.

Additionally, an aggregates train runs overnight between New Haven and Long Island.This is operated by a railroad which isn't in TSW, but for gameplay purposes it seems they've borrowed some locomotives from CSX temporarily to handle the service.



In total, there is over 18 hours of freight gameplay split across 25 services, all of which is included with no other add-ons required. Each of the three assignments is split into segments of about an hour long, so you can work your way through the shift over several play sessions, or continue straight to the next task (after a built-in five minute break to give you time to stretch your legs and restock on snacks without worrying about falling behind).

Adding to the action at Grand Central with the M7A and M3A


Grand Central Terminal comes to life if you own the Harlem Line route, providing the M7A and M3A to operate Harlem and Hudson Line services. Trains which stop at Yankees-E 153rd Street, Botanical Garden, or Fordham are playable, about 150 in total, while the rest appear as AI trains. Some of the playable services are deadheads which go around the upper-level loop at Grand Central, so keep an eye out for these!

Both the M7A and M3A have been updated to support the latest version of ATC and ACSES, the Positive Train Control system used by commuter railroads in the northeast, as well as support for a new feature in American routes...

Dinah, won't you blow your horn?
Metro-North requires engineers to blow one blast of their horn when approaching station platforms, between the hours of 6 am and 9 pm. We've implemented this feature for AI trains at all stations in Metro-North territory.

Engineers will also blow warnings for employees working on the ground at several locations throughout the route, such as yards or where maintenance equipment is parked close to the track and track workers may be nearby. This warning is one long and a short, and can be followed by repeating two shorts until past the work area. We hope that you will also follow these guidelines for the safety of our NPCs.

A view on railfanning


Speaking of maintenance equipment near the tracks, you'll notice orange bucket lifts placed throughout the route. If you've ever wanted to elevate your railfanning experience, walk over to a lift and find the prompt to sit in the bucket!
For reference, you'll find these lifts at:

• Harold Interlocking, east of Sunnyside Yard
• Mott Haven wye
• New Rochelle Yard
• Cos Cob MOW Track

Game Day Specials


Don't feel like commuting to work? Take the train to a sports game! Operate the M8 or M7A to Yankees-E 153rd Street for baseball games, or the New Jersey Transit ALP-46 and Multilevel cab car to Penn Station, en route to a stadium in the Meadowlands of New Jersey. We'll let you imagine who wins each game, but don't forget that the fans have to get home, too! (There's special NPC spawning logic at Yankees-E 153rd Station to flood the station with passengers after the game ends).

The Scenarios


The route includes four M8 scenarios and one ACS-64 scenario.

Student Engineer (M8)
You've recently transferred to the New Haven Line and are joined by a road foreman to cover operating details and points of interest on your run to Grand Central Terminal.
