If option RAILWAYS is disabled, a sector has railroad track as long as
its rail infrastructure efficiency is non-zero. Train mobility cost
depends on rail infrastructure efficiency (see \*Qinfo Mobility\*U).
-Spy reports show the rail infrastructure efficiency in colum \*Qrl
-eff\*U.
+Spy and satellite reports show approximate rail infrastructure
+efficiency in column \*Qrl eff\*U.

If option RAILWAYS is enabled, all highway-like sectors are railways,
and the track is operational as long as the sector is at least 5%
zero (column mob cost in \*Qshow sect s\*u). Operational railways
additionally extend track into adjacent sectors that are at least 60%
efficient. Sector selector track gives the number of operational
-railways within one sector range. This number is also shown by spy
-report column \*Qrl eff\*U. To visualize your railway network, try
-\*Qsect # ?track#0\*U.
