What options exist to manipulate voltage using a Raspberry Pi, above 5v?
Get an ESC (electronic speed control) module. These accept a low-voltage low-frequency PWM signal, or sometimes UART-based digital interfaces such as DSHOT, and produce a proper high-voltage high-...

What options exist to manipulate voltage using a Raspberry Pi, above 5v?
If I understand your question correctly, I think you will need two components/modules:
A DAC that can be controlled by software in your RPi. It seems they are readily available.
A "series-pass&...

What options exist to manipulate voltage using a Raspberry Pi, above 5v?
It is hard to answer your question because I do not know enough about your train engines and track setup. Since I have built several over the years (last one 20 years ago) I will take a SWAG. The PWM ...

GPIO only outputs 1.8V when using Bluedot
You state "the GPIO pins suddenly output 1.8V" - this is IMPOSSIBLE (unless the GPIO is grossly overloaded). For a lightly loaded circuit the GPIO output will be >2.5V or <0.8V.
It is ...

Where is the configuration setting for enabling and disabling low voltage warnings in Bullseye 64 bit?
Further investigation has shown that this appears to be a solution. It appears to suppress kernel messages:
sudo dmesg -n 1

You fix it by getting an appropriate supply.
There is no way to disable it.
The low voltage is detected in hardware and actioned in firmware.

Insufficient power for RPI + 7" Touch Screen
Your battery pack does not supply enough power. The recommended minimum is 2.5A for the Pi, the fact that it even runs is luck. I have seen from 2A to 3A recommended. My best recommendation is get a ...
