The Capital Red Rose Corridor, previously known as CORRIDORone, was the first corridor identified for development in a regional mass transit system.  A 37.4 mile span from Harrisburg to Lancaster, this corridor encompassed residential communities, employment centers, educational facilities, cultural amenities, and arts and recreation attractions that were studied for development of a regional commuter rail network. 

This corridor has benefited from upgrades made to Amtrak’s Keystone Corridor through their partnership with the Pennsylvania Department of Transportation. From the Harrisburg Transportation Center to the Lancaster Train Station, Amtrak's ridership has experienced double digit increases while serving the existing rail stations in Harrisburg, Middletown, Elizabethtown, Mount Joy, and Lancaster. PennDOT is currently working on plans to construct a new rail station near Harrisburg International Airport.

While there doesn’t seem to be the political will nor the funding available at this time to construct a new regional commuter rail system, the MTP is heartened that Amtrak and PennDOT have made the commitment to increase service in this corridor.
