R013, also previously called the Greenslade Shuttle by fans, is a Waterline route that runs from Benton to Greenslade. The route takes only 5 minutes to complete and it has a length of only 1.92 miles (3.09 kilometres).
This used to be both the shortest Waterline route and the shortest route in the game in terms of length (3,089 metres), but R015 now holds the title (1,705 metres).
Though in V1.8, R043 (Leighton West <> Leighton City) took over the record, being shorter than the 2 routes above with a length of only 692 metres.
This route earns the most Points-Per-Minute (PPM) on average, at 6 PPM, provided that there are no delays at any point in time.
Two stations on this route, Morganstown Docks and Whitney Green, are long enough for only 3 car trains, with the 4th car hanging off the edge of the platform, meaning the Class 379, Class 319 and Class 165/1's 4th car cannot fit into those stations.
Along with routes R015 and Stepford Connect's R029, the highest speed-limits throughout the entire route are only at 75 MPH or lower (to match the max speed of the lowest max-speed trains).
