Accuracy issue on the NS 1200

Bericht door exoskye »

Hi,

I just noticed something that's honestly really annoying me.
In reality, when you move the regulator in a DC locomotive such as the NS 1200 (which appears to function similarly to the EM1 and EM2 aka NS 1500), the regulator simply changes the amount of resistors in the circuit. In the EM1's case (and I assume it also applies to the NS 1200), this adds more resistors in parallel for every notch added, lowering the resistance and thus allowing more current, but at the same also increasing the amount of resistors in the circuit, causing each to carry less current individually, reducing the heat produced per resistor.

This also means that, as the locomotive speeds up, the current naturally drops.

In-game, the NS 1200 in expert mode seems to simply have the regulator directly controlling the current going into the motors, with the full-field notch on the series-parallel mode (einde fase 2) drawing exactly 96.9 amps, no matter what you do. This also means that, from what I can tell, it's not possible to get up to the full-field notch on the parallel mode (einde fase 3), since you just draw too much current and the locomotive overloads.

This also happens with the NS 1200 Enhancement Pack, but I don't believe that's supposed to change it anyway.

I don't really know what to do about this, it just feels.. inaccurate, and really breaks the immersion, which is a bit silly for a locomotive with an "expert" mode.

Maybe someone can take a stab at fixing this? I don't know how easy of a fix it'd be, though, given I assume that's something scripted into the locomotive.

(If this is the wrong place to put this, please let me know, I'm new to this forum)
Just a silly cheetah on the internet, making TSC stuff and, as of recently, enjoying Dutch TS content!
