NS 4100 leads priority intermodal 28N eastbound on the NS Sandusky District. It is seen here crossing the CSX Mt. Victory Subdivision as it comes through Marion.

As the fog thickened and a cool air come over us at the east portal we had no questions as to if a train was coming, just how far in the 4.75 mile long tunnel was the biggest question

First of two 28Ns comes east by Wachusett Station

Pan Am Southern autorack train 28N enters the yard limits in Gardner MA at Parkers, milepost 346.

After doing some work in Gardner, 28N runs light back to the rest of his train with the conductor riding on the rear of NS 2521 a former Conrail SD70.

The chase continues as 28N cruses through Otter River, MA at a steady 25MPH.

The chase is on! NS 1066 leads 28N through Deerfield Yard for the first time.
