It’s already a low gravity planet and I’ve seen electric rail climb some annoying steep roads.
It's a game, it's fun, I really don't care deeply beyond the craic of taking a position.
Changing the graphics to show a rack and pinion on the ramps (and short sections before and after the ramps) would be a knowing nod in the right direction that I'd endorse, sure.
IRL, however, we're not going to see a rack and pinion lift a 250 wagon x 100 tonne load 2.5 kilometre long iron ore train up a short one story high incline (throw in the engine and the wagon weight that's ~ 30,000 metric tonne).
A 2.5km iron ore train? What are you talking about? A 2-8 train in Factorio is 10 wagon-lengths, and each wagon is 7 tiles = 7 meters, so a large iron train is only 70m long.
You can see video if you look for Pilbara ore trains.
In game - short ramps lifting 30 feet are cute and look like fun in a tile based game. In real physics the inclines are much more gradual, especially for loded ore cars.
Although I do recognise the awesomeness of early victorian wide valley crossing bridges (which didn't come cheap, then or now) and the jaw dropping bridging a valley with a canal (water ain't light .. but at least it doesn't vibrate).

I've played Factorio for 1800 hours. I'm already in hell.
Yes, it's a game, yes there are many things that are real world simplifications, all that I can live with.
Trains going up short one story high ramps with no slippage or rack railway hurts my brain - laden freight trains even more so.

Blessings be upon you and may you not end up in hell.
