Public universities are free in my third world country.
You can view the trains from the labs and classrooms.
The campus was originally, erm "train infraestructure zone" along the rails. The main building on campus are reutilized train infraestructures, for example the "Tornavías" was an old circular train garage, with the interchanger still inside.
The new buildings are constructivists

Anyways, if any 'murican chapo looking for selling a kidney to study medicine, universities are free here, and a person can live decently with 350 US$/month renting an apartment. You need to understand spanish, tho
I'm actually struggling to understand why this wasn't implemented at my university that has three campuses about ~5 miles apart from eachother and claims to be a great engineering college yet uses shitty busses to ''ensure'' students are able to get from one campus to another without missing five minutes of class
Building tracks from scratch is maybe expensive. In the case I showed, they used an obsolete siding track .
