Route L – Lemoyne Shuttle routes have shared stops in downtown Harrisburg with the Rabbit Transit York/Harrisburg commuter bus route, the RabbitEXPRESS. Rabbit Transit is CAT's counterpart public transit agency in York County. Most of CAT's routes also connect at multiple locations in downtown Harrisburg with rush hour, commuter bus routes operated by R & J Transportation. R & J Transportation runs two Schuylkill County/Harrisburg routes. In Hershey, the Route 322 connects with selected bus routes within the County of Lebanon Transit Authority or COLT system. COLT is the transit provider in Lebanon County. Connecting routes include COLT's Route 8, which connects with the CAT Route 322 at Tanger Outlets Hershey and COLT's Route 18, which shares stops with the Route 322 at various locations within the village of Hershey and at the Penn State Hershey Medical Center. COLT also has "Twilight Run", evening service on the Route 8 that connects with CAT's Hershey route. Finally, the Route 7 (Middletown) stops on some of its runs at Harrisburg International Airport, the primary commercial service airport in South Central Pennsylvania. Most major U.S. passenger airlines, excluding dedicated low-cost carriers, have flights to/from HIA. Proposed commuter rail services Capital Red Rose Corridor (Corridor One) In late 1999, CAT's board of directors voted unanimously to pursue the vision of bringing commuter rail to the Harrisburg metropolitan area. The project, initially named CorridorOne, will provide regional rail service along existing rail facilities within the lower Susquehanna Valley, linking Lancaster with Harrisburg. Original planning of the corridor would have extended service along a 54-mile stretch between Lancaster, Harrisburg and Carlisle, Cumberland County; however, the Harrisburg to Carlisle segment was dropped from the proposal in 2005. Project schedule Preliminary engineering and environmental studies phase – completed August 2006 Final engineering design phase – est. 2009 Construction phase – complete late 2010 (est.) Lancaster to Harrisburg service – operational late 2010 (est.) Corridor Two CAT and the Modern Transit Partnership began discussing a second commuter rail corridor in 2009, designated Corridor Two. Corridor Two would operate between York, Harrisburg, and Lebanon. There may be difficulties implementing the Harrisburg-Lebanon segment of CorridorTwo, as this segment would operate on the heavily traveled and fast-growing Norfolk Southern Harrisburg Line, an east–west trunk line in Norfolk Southern's freight rail system. Norfolk Southern has discussed upgrading and potentially expanding capacity of the Harrisburg-Lebanon segment of their system for freight rail operations as
