Electric acceleration is too strong
The speed of the train MK1 is 130, and the speed of the train MK3 is 259, but if the electric power is used, the acceleration and speed are doubled, and the speed limit without fuel is better than the consumption of electricity
At the same time, there is not much difference between nuclear-powered trains, hybrid fuel trains and ordinary trains except for the use of fuel, and the nuclear-powered train is too heavy because of the weight of 20k, so the braking is slow. I think these should be balanced.
At the same time, when I tested it, the electric train could not reach the maximum speed of 518 when using the MK3 freight car, but was worse than the ordinary car.

I don't understand what you're saying the issue is here.

At the same time, there is not much difference between nuclear-powered trains, hybrid fuel trains and ordinary trains except for the use of fuel, and the nuclear-powered train is too heavy because of the weight of 20k, so the braking is slow. I think these should be balanced.

The difference in fuel usage is the point. The nuclear trains also have higher acceleration power. I can bump up their braking power.

At the same time, when I tested it, the electric train could not reach the maximum speed of 518 when using the MK3 freight car, but was worse than the ordinary car.

Yeah I can fix that.

The speed of the train MK1 is 130, and the speed of the train MK3 is 259, but if the electric power is used, the acceleration and speed are doubled, and the speed limit without fuel is better than the consumption of electricity

I mean if you use electricity as fuel, the speed and acceleration will double, but using rocket fuel or even nuclear fuel will not double the speed, which makes these fuels meaningless
So I asked Deepseek how to set the value of electric fuel: it gave the answer

"According to the actual situation, the performance of electric-driven trains in acceleration and top speed can be based on the following analysis:

Acceleration correction: The electric motor can provide instant high torque, making the train acceleration performance significantly better than traditional diesel power. In reality, the acceleration of electric trains is usually 1.5-2 times faster than diesel. If the diesel in the game is set to the baseline 100%, rocket fuel is 180% (short-term high thrust), and nuclear energy is 250% (continuous high power), then electricity can achieve high-efficiency energy. For conversion and continuous power output, the acceleration correction should be close to or exceed that of nuclear energy. Considering the instantaneous response of the electric motor, it is more reasonable to set the acceleration correction to 220%**.

Maximum speed correction: The maximum speed of electric trains is limited by the power supply system and motor design, but is usually higher than that of diesel trains. In the game, the maximum speed corrections of rockets and nuclear energy are both 115% (probably based on unified balance), so electricity also uses the same ratio to reflect its speed advantage in reality, but in accordance with the game settings, the maximum speed correction remains at 115%.

Final answer:
Acceleration correction: 220%

Maximum speed correction: 115%"

Considering the quality system in the game, if higher speed is pursued, then high-quality nuclear fuel and rocket fuel are still valuable, which can allow the train to achieve a higher maximum speed.

I mean if you use electricity as fuel, the speed and acceleration will double, but using rocket fuel or even nuclear fuel will not double the speed, which makes these fuels meaningless

No it doesn't. The whole point is electricity is better, but it requires setting up the infrastructure for it. Hybrid trains are not supposed to be equal. Trains that use non-electric fuel are not supposed to be equal.

So I asked Deepseek how to set the value of electric fuel: it gave the answer

I don't know why you asked an AI anything. Nothing in it's answer is at all relevant, because it doesn't take into account the gameplay I'm aiming for.
