Train Sim World 7: LIRR M3 EMU Add-On is a simulation title for PC that adds the Long Island Rail Road M3 electric multiple unit to the series roster. This two-car EMU brings players into the role of operating a classic commuter train on electrified third-rail routes around New York.
Gameplay
The core experience centers on realistic train operation with the M3 EMU. The vehicle stretches 85 feet per car and runs on direct current from the third-rail system, powered by four 160-horsepower traction motors. Players manage acceleration, braking, and speed limits up to 80 mph while following signals and route conditions on the Long Island Rail Road network.
Controls emphasize authentic handling through a highly detailed cab that includes accurate instrumentation and systems. Sound design draws from recordings of the real equipment, capturing the distinctive electric operation. The add-on integrates with the existing LIRR route, allowing the M3 to run alongside other services in the simulation environment.
Performance modeling uses the SimuGraph vehicle dynamics engine to replicate traction, braking response, and overall behavior of the stainless-steel married-pair units. An interactive training module introduces the controls and procedures specific to this EMU before players attempt full runs.
Game Modes
Scenarios provide structured sessions with defined objectives, such as reversing peak services, handling maintenance moves, and managing multi-train weaves on the route. Three dedicated scenarios come included with the add-on.
Timetable Mode layers the M3 into scheduled services across the Long Island Rail Road, letting players select and complete passenger runs that fit into the broader daily operation. The add-on extends timetable functionality to support the new EMU on both original and updated versions of the route.
Free Roam allows players to spawn the M3 independently and explore the network without fixed schedules, creating custom journeys or testing handling in varied conditions. The content remains compatible with later series updates, including Train Sim World 7.
Route and Vehicle Details
The M3 EMU entered service in the mid-1980s as part of a fleet expansion by the Long Island Rail Road and Metropolitan Transportation Authority. These units continue in operation today, distinguished by their yellow, gray, and silver livery. The simulation captures the 174 cars built by Budd, including their General Steel GSI trucks and overall dimensions.
Operation requires the separate Long Island Rail Road: New York - Hicksville route add-on. Once installed, the M3 functions across compatible route versions and adds timetable services to the commuter network stretching from New York terminals into surrounding suburbs.
Is It Worth Playing?
This add-on suits players who already own the required LIRR route and seek additional variety in commuter operations. It delivers precise modeling of a specific historic EMU with three scenarios and timetable integration that extends playtime on the existing network.
Reception for the content has been mixed in user feedback, reflecting the specialized nature of the simulation. Those interested in detailed cab work, authentic sounds, and realistic third-rail handling on Long Island services will find the most value. Newcomers to the series benefit from the included training module before progressing to full scenarios or timetable runs.
The add-on maintains compatibility with Train Sim World 7, ensuring continued support for the M3 EMU within the current version of the simulation. It provides focused content rather than broad new features, making it a targeted purchase for route owners.
