Mossline

Drive a coastal railway in a free 3D train simulator. Complete six passenger and freight duties, brake for stations and unlock free driving.

Drive from the harbor to wooded hills in a 3D train driving simulator with six original duties. Carry passengers, haul loaded timber wagons and return downhill through sunset or rain. Use power, coasting and brakes to follow speed limits, wait at red signals and stop beside each platform marker. Cab and chase cameras show the same railway and its freight branch. Complete every scheduled stop to unlock the next duty. Optional medals reward precise stops, a smooth ride and the target schedule; arriving late alone does not end a duty. Complete all six to open free driving without station calls or medal targets.

How to play

Drag up/down and hold / W/S or arrow keys

Choose a duty and press Depart. Drag upward in the scene and hold for power, downward for brakes, then release to coast. Keyboard players can hold W or Up for power and S, Down or Space to brake.

Watch the next-stop distance and speed limit. Brake before red signals and wait for green. Stop beside each platform marker (the closer, the better your medal) and wait for boarding or loading to finish.

Serve every listed stop to complete the duty and unlock the next. Tap the scene for the horn, use the camera control or C to switch views, and pause with the pause control or Escape.

The six duties build on each other: Harbor Local makes one stop at Mosswood, The Ridge Climb adds a held crossing signal and a climb, All Stations serves every platform, Timber Train hauls loaded freight, Sunset Express runs downhill at dusk and Rain on the Rails brakes on wet rails. Completing all six opens free driving.

Tips

Release power before reaching the speed limit. The train keeps rolling when you coast, and downhill stretches need earlier braking.

Loaded freight and wet rails lengthen stopping distance. Approach the marker slowly and hold the brake until the doors open or loading begins.

A completed duty counts even with no medals. Replay it for stopping accuracy, smooth driving or the optional schedule target.

Once the train is at rest beside the marker, release power completely. Boarding and loading begin only when the train is stopped with no power applied.

For the On the mark medal, your stops need to average within about 2.5 meters of their markers. For Smooth ride, stay under the limit and brake early and gently instead of holding full brake at speed.

Can I play this train simulator online without a download?

Yes. Mossline runs inside the page in a browser with WebGL enabled. It is free and needs no account or app. Touch and mouse players drag directly in the scene; keyboard controls are also available.

Is there a time limit?

Each duty has an optional schedule medal. Arriving late does not fail the duty. Passing a required stop or red signal, staying far above the speed limit, or reaching the buffers too quickly can end an attempt.

Does Mossline save my progress?

Completed duties, unlocked duties and best medal records are saved in this browser when storage is available. An unfinished drive starts over after reloading. Clearing site data removes the save.

How do I unlock free driving?

Complete all six duties; medals are optional. Free driving offers the harbor-to-ridge line, the return trip in rain and the timber freight branch. There are no required station calls or medals, but speed limits still apply and you must stop safely at the end of the line.

What makes the freight and rain duties harder?

Loaded timber wagons accelerate more slowly and need roughly 1.6 times the stopping distance of a passenger train at the same speed. Wet rails need roughly 1.5 times. Start braking earlier on both, and watch the next-stop distance rather than the platform itself.
