About this app

Master the sounds and behavior of commuter trains, the backbone of urban railways.

This sound app works in conjunction with the MTCSMINI console (sold separately) to control model trains with realistic behavior. It faithfully simulates the rich motor sounds and detailed equipment operation of JNR-style commuter trains.

■ Key Features
Motor Roar: Realistically reproduces the distinctive roar that increases with speed.
Blower ON/OFF Function: Reproduces not only the cooling sound on above-ground sections, but also the "blower-off" mode like subway direct trains.

Realistic Control Logic: Equipped with logic that allows trains to run even when the blower is turned off. Enjoy precise operation tailored to specific series and operating situations.

Selectable Door and Engine Sounds: Select and change the door opening and closing sounds that vary by car. You can even capture the unique differences between individual cars.

■ Features

Recreate JNR-type commuter trains that operated throughout Japan, from the Yamanote Line to the Osaka Loop Line and even subway direct lines, on your smartphone.

Even if you don't own the MTCSMINI console, you can enjoy the sound alone in simulation mode.

Two-handle operation provides the unique acceleration and deceleration feel of a resistance-controlled train.

*An MTCSMINI console is required to control the model trains with this app. (The audio function works independently.)
*For purchases and details, please contact your local retailer.
