Assuming too much and neglecting too much is a professional sickness of physicists. For a N-S railroad in the trade wind zone I would expect the east side of rail to be worn more. And the Coriolis effect would be indeed responsible for that Did I pass your "exercise"? But I'm not a railway engineer, what I expect here doesn't have much importance. Neither you are, BTW.

I found something.
The Wikipedia article on the Coriolis Force has an entire section
involving an east-west train on the equator.
https://en.wikipedia.org/wiki/Coriolis_force#Intuitive_example
Summary: An eastbound train has the Coriolis force pointing away from
the axis of rotation, or up, making the eastbound train lighter than the
stopped train. For the westbound train moving against the earth's
rotation, the Coriolis force is downward, and would make a westbound
train appear heavier.
For a high speed object, this becomes the Eötvös effect, which causes a
westbound projectile to be deflected downward and an eastbound
projectile upward, when compared to the expected ballistic path ignoring
rotation.
("Eötvös" conjures other thoughts about Uncle Al, his idée fixe about
asymmetries had "Eötvös" in its name)

Uncle Al's as well as any other idealistic discussion about rails and
trains neglects the overwhelming irregularities attendant to the
operation of trains on standard railway tracks.
There's nothing as valuable to such discussions as watching trains
operate at various speeds. Almost as valuable is riding some trains.
I'd wager that most of the participants here have never ridden a train
let alone ridden enough trains to get a reasonable sampling of what
actually happens.

CMIIW but surely the Coriolis force does not exist right on the equator. Travelling east or west should not be effected. -- -- lover of truth

Nothing can ever be wrong if she learned it... science is backward instead. Look at how young it is. Modern is ancient still... Coriolis force has a boundary where it converts to its opposite in an first instant crossing it. Weather turns round according to Coriolus where it forms. It does not go away.. it flips immediately crossing the equator both ways... Mitchell Raemsch

We have an ideal train running on a perfectly aligned East-West track, at a latitude of 45 degrees. Will there be unequal wear on the rails? Does it matter whether you look at the East to West or the West to East track? Jan

What of the fundamental four forces is it? No. Coriolis is a motion law not a force. What pushes it?

A Foucault pendulum at the equator will not rotate, no matter what direction it swings in. Those demonstration experiments for the tourists, with emptying wash basins or coke bottles going clockwise or anticlockwise when going some distance away from the 'equator' line on the ground are faked, [1] Jan [1] And that 'equator' line on the ground is usually in the wrong place too. (and GPS-equiped tourists notice)

My new nephew-in-law* told us about the "fake Equator monument" and the "real Equator site" and we went to both places. The "fake" equator is a big park with a big monument with a sideways globe (a perspective rarely seen) on top, with a line in the pavement purportedly right on the equator with a big "N" and "S" on each side, plus monuments to the heroes of Ecuador, tourist trap souvenir stores, etc. It's the site the Spanish determined was on the equator in the 1600s. It's actually about 1/4 km south of the actual equator. The "real" equator site is close by and appears to be run by indigenous people and is as much a museum to their culture as to the equator. It has those tricks of draining the water on each side of the equator, balancing an egg on the equator and other tricks. I told my wife and kid those demonstrations are all fake but play along. I placed my phone on the marked equator and it claimed it was a few dozen meters south of the equator. I estimated the actual equator was about on the double yellow line** on a fairly busy road at the entrance to the place, but wasn't about to stand in the middle of the road and place my phone there. (*) We were there for the wedding of my niece. My nephew-in-law is a native of Ecuador and Colombia, his g-grandfather was a president of Ecuador. (**) Ecuador can be more US friendly than many other countries. They use the US dollar, not their own currency, the power is US standard 120VAC 60 Hz with US style outlets and the road markings look like US roads. Although they speak Spanish and some native languages many know English and seem to like US people.
