JNR 103 series and MT55 traction sound MOD

JNR 103 series and MT55 traction sound MOD

Sound upgrade MOD for JNR 103 series EMU and various MT54 traction EMU to add multiple sounds. For example, doors open-close or resistor cooling fan blower. Currently compatible with 103 series EMU MOD.

The MT55 is a DC traction motor for Japanese National Railways EMUs developed in 1962. It was designed for use on commuter lines with short distances between stations, with good acceleration and deceleration and low power consumption, even when half of the cars are powered and half are not. It was used in 103, 105, 301, 119, and 121 series EMUs. Depending on the production period, there are two types: one with a low motor cooling noise and the other with a high motor cooling noise.

Since the specification of the sound set is completed within mod.lua, it does not affect the file structure of the default sound source for each mod. If you do not use a sound mod, simply remove this mod to return to the default sound set.

Compatible MOD lists:
103 series (by masubo) and Max’s Fix
103 series (by YOMITI)

Oct. 25, 2022: YOMITI’s 103 series is now supported. Now, Masubo’s 103 series and modified mods are optional.
Dec. 16, 2021: Removed performance fix to prevent mod conflicts. Now it can be used with MaxC’s fix mod “103 Series Max’s Fix”. Sort by Masubo’s original, MaxC’s fix, and this sound mod. Localization into Japanese has not been completed.
October 30, 2021: Sound updated. Canary and Emerald Green trains now have low-pitched motor sounds, and the door closing sound is now a conventional type, with the load-compensating device sound coming first.

The modified mod, by MaxC, includes the following fixes. I used to have a similar performance fix on mod.lua for this sound mod, but it would crash when used with MaxC’s mod, so I removed these settings.

Power output and tractive effort fix
The output of the electric cars was set at 800 kW per car, so it was reduced to 440 kW.
Power output and traction force are set to 0 for the trailer.
Weight fix
electric vehicle: reduced from 96 tons to about 40 tons.
Trailer vehicle: reduced from 96 tons to about 30 tons.
Car types fix
In the Multiple Unit, a single car that was supposed to be a powered car without a panto graph was designated as a non-powered car, so it was corrected to be a powered car.

To be compatible with the modified mod by MaxC, the following functions will be removed.

The tractive effort of 100 kN to approximately 42 kN.
In the Bantan Line variant, both cars of a two-car formation are powered, so the output and traction power are set for the front car without a panto graph.
