Tokyo Train Loop Build a circular railway that loops around Tokyo ----- Gradually add more trains to the city, extend the tracks, connect the stations, and eventually complete “one great circular loop” around Tokyo. Tokyo Train Loop is a route-building simulation game set in Tokyo, where you can sit back and watch a world of endlessly running trains while nurturing your very own circular railway. ----- Watching trains loop around is deeply satisfying On screen, trains travel quietly—and steadily—through the streets of Tokyo. What begins as a short stretch of track grows longer as you play, eventually developing into a full loop that circles the city. As trains increase, formations grow longer, and the rails finally connect into one continuous circle, feel the satisfaction of completing the loop. This game is designed to make the process of building the loop itself enjoyable. ----- Extend the rails and expand Tokyo Your actions are simple:  Add train cars  Extend the tracks  Improve facilities  Create new trains With just these, the city and its railway will naturally grow. No complicated controls or confusing systems. Easy to enjoy with a few taps—or even just by watching. Designed so anyone can play comfortably. ----- A Tokyo that shifts from day to night The city changes with time. Morning, daytime, evening, and night— the light and atmosphere gently evolve as the hours pass.  Bright daytime Tokyo  Rails glowing in the sunset  Trains and city lights shining at night Even simply watching the trains run as the scenery slowly changes can feel surprisingly calming. ----- Play at your own pace, as long as you like In Tokyo Train Loop, there’s no pressure. No rankings to chase, no demanding gameplay, no difficult controls. Perfect for:  Players who want to progress little by little  Fans of trains and city scenery  Anyone who enjoys relaxing, watch-and-play games Whatever your style, the game is built to match your pace. ----- More and more to unlock over time As you progress, Tokyo becomes livelier with:  New types of trains  Changes in train formations  Expanded routes  A busier, more vibrant city A city that starts quiet, then slowly fills with trains— watching that transformation is part of the charm. ----- “Completion” isn’t the end Even after the circular loop is complete, the journey continues. You can keep developing the route, add more buildings to create an even more beautiful cityscape, and shape Tokyo into the world you want to see. A city you can keep watching for as long as you like— that’s the Tokyo we aim to build. ----- Tokyo Train Loop is perfect for players who:  Love trains and railways  Enjoy steady, incremental growth  Want short, relaxing play sessions during busy days  Are looking for a calming game to watch and unwind If any of that sounds like you, this world is waiting. ----- Complete your own circular railway around Tokyo. Together with trains that never stop, why not grow Tokyo’s city and rail network— slowly, gently, at your own pace? Sound effects provided by https://otologic.jp

Verdict

The call

The clearest difference is in-app purchases: Idle Tokyo Train Loop at none against Subway Train Simulator's 3. Idle Tokyo Train Loop also leads on update cadence (weekly vs every 5 weeks) and review sentiment (100% vs 85%). Subway Train Simulator's advantage is ratings volume (244 vs 7) and rating (4.3 vs 4.1). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Subway Train Simulator holds the better App Store score, 4.3 against 4.1. That said, the two scores are not equally well evidenced: Subway Train Simulator has 244 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 85% of Subway Train Simulator's written reviews are positive against 100% of Idle Tokyo Train Loop's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Subway Train Simulator ships an update every 5 weeks, Idle Tokyo Train Loop weekly. The most recent releases landed on October 14, 2026 and October 11, 2026 respectively.
