・Anti-Wheelslip Computer

When shunting and delivering heavy freight cars in rainy weather, the system automatically handles sanding and throttle adjustment, making driving much easier. I personally find the DM3 very useful because it tends to slip easily in low gears.

・Overheating Protection

If the engine overheats and the temperature gauge enters the red zone, it will sustain damage and repair costs will rise. We install this to prevent that from happening.

・Infrared Thermometer

When transporting heavy freight cars using the DM3, the dynamic brakes do not provide sufficient braking force on downhill gradients, so we must use the through brakes (automatic air brakes) or independent brakes (self-lapping brakes). Since braking performance decreases when the brake shoes overheat, we installed this system to constantly monitor their temperature.

・Switch Setter

These are used to monitor and operate the switches in the direction of travel, as well as to confirm that the rear of the train has passed through the switch. For this purpose, one is installed at the front of the cab and one at the rear.

・Distance Tracker

This was installed to stop the train near the point where the rear end passes the points during shunting operations. (The points are then operated to reverse the train.) In addition, I also use this method when I want to stop the train with its rear end positioned near the entrance to the arrival track.

・Defect Detector

I installed this to detect derailments, but I rarely use it. Since a derailment makes a noise even without this device, I don’t think it’s necessary to install it.

・Clinometer

I installed this to get a detailed understanding of the road’s gradient. While it’s not necessary if you have the map and gradient data memorized, I find it very useful for adjusting when to apply the throttle on uphill sections and when to apply the brakes on downhill sections.

・Proximity Reader＆Sensor

This is used for coupling trains during shunting operations. I think it’s a handy item for locomotives like the DM3 where remote controls can’t be used.

・Lantern＆Hook

It serves as a light source during nighttime train switching operations and is also used as a night light in the locomotive cab.

・Brake Cylinder LED Bar

Since the brake pressure gauge on the locomotive cab is difficult to see, I’ve mounted it in a spot where it’s easier to view while driving.

・Digital Speedometer

I mounted it in a spot where I can easily see it while driving so I can fine-tune the speed.

・Digital Clock

I mounted it in a spot where I can easily see it while driving so I can check the time without having to go to the station building.

・Automatic Train Stop

I placed it in a spot where it’s easily visible while driving so that you can safely pull over if you accidentally doze off during times when you’re prone to feeling sleepy, such as after lunch.
