About this game
Enjoy the charm of one of the UK’s oldest and most enchanting railways from the best available viewpoint – the driver’s seat!
Hammer through urban sprawl, rolling fields and famous tunnels at 90 MPH in all weathers and at any time of your choosing.
Built by rail simulator enthusiasts ( in tribute to “Southern Belle” ), Train Operator 377 is inspired by footage based training simulators and emphasises realistic driving performance including dynamic signalling, weight and weather dependent braking, operational safety systems and even hazards on the line!
This is a free version of our full simulation, also available on Steam. The full simulation is payware and provides the entire Brighton Main Line ( London Bridge branch ), drivable in both directions.
This free version features the line from Brighton to Three Bridges and it's only possible to drive north bound.
Otherwise, the feature sets are identical.
Simulation Features:
Over 20 miles of track.
Uses film footage, blended with computer animation, to provide scenery.
Drive a variety of services, any time of day, for every season.
Multiple weather themes with a variable weather generator.
Dynamic and unpredictable signalling.
Multiple views from the driving position, plus a configurable HUD.
AWS and many other systems featured, including a (simplified) onboard computer.
