TS or RA2? In TS, the editor should have an option to place it and you can select if from the overlay menues anyway. In RA2, you need to use FA 0.98 to place it as the overlay list is crippled in FA2+. However in RA2, the track is the TS track and is still in the TS terrain pallet so it looks odd. The train units don't exist either so its really no point in RA2 with the exception being with the TX v1.4 which is in development (to get tracks) or the mod under the development title "The Project" for all the train features which is yet to be completed and needs mappers to make SP missions for yuris side.
