Is your feature request related to a problem? Please describe.
Railroads are need to be manually placed, but seeing what tiles have railroads is difficult. They are rendered under everything else (if at all) and having broken rail lines is common.
Describe the solution you'd like
A lens showing railroads brightly highlighted would help identify gaps. Preferably this would auto-select when selecting a Military Engineer. Highlighting existing railroads seems more effective than highlighting where railroads could be built, with the exception of cities: city tiles without railroads that are adjacent to tiles with railroads could be highlighted red, as (I believe) the need to build road/rail underneath cities is new in Civ 6.
Describe alternatives you've considered
A more general "transportation" lens may be useful, with rails, roads of different effectiveness, mountain passes, airports, etc. Alternatively/additionally, the lens could a Military Engineer specific lens, similar to the Builder's lens.
Non-lens solutions would be making the railroads render much more clearly, consistently, and correctly, as they're currently a messy smear of railroad spaghetti across your empire!
