[0.13.x] Train Schedule - Cargo-always display

[BlackKnight]

When clicking a Train Schedule, if in a specific proximity to a locomotive, the schedule also displays the Cargo button. But the proximity correlation isnt initially obvious since now accessing a train schedule can be done from anywhere on the map. Thus for better clarity, I would like to suggest to display the cargo text at all times instead of hiding it (just disable access). Alternatively, access to the cargo window could still remain when out of proximity but the cargo window would just be non-interactive once displayed - useful for checking fuel.

See image for reference. Current: a1>a2, Proposed: b1>b2
See my related suggestion on adding a fuel gauge/summary to the main train schedule.
