Rumoi line
Introducing
The Rumoi Line is a 14.4 km long JR Hokkaido line connecting Fukagawa Station in Fukagawa City, Hokkaido to Ishikari-Numata Station in Numata Town, Uryu County, Hokkaido.
The line used to run 66.8 km to Mashike Station in Mashike-cho, Mashike-gun, Hokkaido, but the Rumoi - Mashike line was discontinued in December 2016, followed by the Ishikari-Numata - Rumoi line in April 2023, leaving only Fukagawa - Ishikari-Numata as the only remaining line.
In the past, the Rumoi Line was serviced by the express train "Mashike," which runs directly from Sapporo Station, the express train "Rumoi," which runs directly from Asahikawa Station, and the "SL Suzuran" steam locomotive, a C11 class steam locomotive. As of March 2024, only seven regular trains per day operate on the in-bound line and out-bound lines.
Departing from Fukagawa Station, the train heads north through the Ishikari Plain, crossing the Ebishima Pass with its series of large curves and gradients on its way to Rumoi Station. Along the way, you will be able to experience Hokkaido's unique character in many places, such as Kita-Chippubetsu Station with its wooden platform and Ebishima Station adjacent to the station building where the TV drama "Suzuran" was set.
This DLC includes the in-bound line and out-bound lines between Fukagawa and Rumoi, including the discontinued section. We have decided to create this DLC not only as a driving experience, but also to preserve the scenery and memories of the discontinued section in the form of a simulator. We hope you will enjoy driving a line that you will never ride again with this DLC.

Console details
On the left, you can see the safety radio equipment.
In the center are several components. At the top is the ATS-Sn gauge, which operates in much the same way as the ATS-Ps. This is only used when departing from or arriving at Fukagawa station.
Then there are various indicators:
- 戸: "Doors closed" indicator
- ↑ : Indicates that the train is moving forward
- ↓: Indicates that the train is in reverse gear
- 機: Lit when the engine is running
- 直: Gear position "Direct transmission".
- 中 : "Neutral" gear position
- 変 : Gear position "Gear change"
- ?
- ATS : ATS-Sn indicator. Turns red when ATS is activated.
- ?
Then there are 3 dials: the speed dial, the ER (?? - black) / MR (Main reservoir - red) pressure dial and the BP (Brake pipe - black) / BC (Brake cylinder - red) pressure dial.
Finally, on the right, you can see the timetable for the chosen route. This is the first line offering direct integration of the timetable into the game.
Special driving features
The KiHa 54 train is different from the other trains in the simulator. In addition to the power lever, you need to manage the automatic air brake and the gearshift lever.
2 modes are available in the simulator parameters (System tab):
- Simplified: Driving is the same as for other trains.
- Realistic: Air brake and gear shifting must be managed manually, see below.
Air brake
Braking is via pneumatic brakes, with a dedicated 4-position lever. Braking power is managed via the right-hand dial and its 2 needles: the red BC needle (Brake cylinder) and the black BP needle (Brake pipe). The 4 positions are :
- Running (運転) [M]: This is the position when the train is running. Release braking force (BC down, BP up).
- Lapped (重なり) [,]: Position to maintain braking force (BC and BP stable).
- Service (常用) [.]: Position to increase braking force (BC up, BP down).
- Emergency (非常) [/]: Position to be used for emergency braking.
The braking procedure is described in the Japanese JRETS manual as follows:
- At about 600m from the next station, switch the lever to "Lapped" [,], to prepare for braking.
- At 500m, switch the lever to "Service" to increase the BC pressure (this needs to be done quite early, as braking takes time to kick in).
- Return to "Lapped" when the BC pressure is between 100 and 150 kPa, trying first to get the BP pressure (black needle) between the blue and yellow zone.
- Finally, as you estimate the distance remaining, switch between "Running" and "Lapped" modes to reduce braking force until the train comes to a complete stop.
Please note that when the brake is "On", there will come a time when the BP pressure may drop, but the BC pressure will not. What's more, if the BP pressure drops too low, it will take longer to release the brakes. It is recommended not to drop below 300 kPa for BP pressure.
Gearshift
This defines the transmission mode between the engine and the wheels. It has 3 positions:
- Shift change (変速): Starting and medium speeds.
- Neutral (中立)
- Direct transmission (直結): Medium and high speeds.
The position is changed via the [R] (to "Direct transmission") and [F] (to "Gear change") keys.
Note that the Kiha 54 automatically manages transmission shifting according to speed, so you just need to be on "Gear shift" or "Direct transmission" before accelerating.
Engine brake (speed limitation)
To use the motor brake (e.g. on steep descents), set the main handle to P1, then press the speed-limiting button [D], and return the main handle to the neutral position.
To deactivate, simply set the main handle to P1 or higher.
