In 2010, the D&H finally negotiated trackage rights under the wire on the NE Corridor from Perryville up to Philadelphia; Amtrak had been convinced to allow freight under the wires just as long as those trains N-E-V-E-R delayed a passenger train, so the Portland Shops pulled out the class L blueprints and updated them for more tractive effort & horsepower, then geared them for a maximum speed of 120mph (instead of the 150mph that #799 is capable of.)
