I did see the post from the user reporting a crash with the mini-trains mod, but logging a new issue as it crashes with all trains. If you switch to the map view, while in a train game crashes with the following error:

The mod Kuxynator's Zooming Reinvented Running (3.3.2) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Kux-ZoomRunning::Kux-ZoomRunning-toggle-map (ID 225)
Entity is not car or spider-vehicle or cargo-pod.
stack traceback:

Actually, you can switch to the map view while in a train just fine, it's when you switch back from the map view it crashes. It's very annoying, even with auto-saves I've lost hours of total game time forgetting this cashes a crash and killing my game. Would love a fix :-)
