U.S. Route 322, a four-lane limited-access highway, lies between Indian Echo Caverns and the town of Hummelstown, where M&H connects with Norfolk Southern Railway's (NS) Harrisburg Line.

PennDOT said it believes more discussion regarding warning devices for the crossing is needed given the volume and type of traffic on Route 322.

Repairs have been estimated to cost between $250,000 and $300,000, and thus the route stops short and no longer reaches Indian Echo Caverns or Hummelstown.

[2] On Friday, January 24, a leased NS locomotive operated by M&H crew delivered a transformer, using line, to the PPL sub station on Fiddlers Elbow Road.

Following extensive track repairs to the line, north of the 322 crossing over the summer, the transformer was delivered by NS Engine GP38-2 #5046.
