take route 10 west from Whippany to route 287 south.
One mile past the route 24 exchange stay in your RIGHT lane and exit to Ridgedale Av / Abbett Ave Morristown....this is the first exit after you turn off 287.
At the traffic light go straight across onto Abbett Ave and go about 1/4 mile, turn left just before the RR Crossing and follow the driveway along the tracks for several hundred feet and you will see the M&E engine house to your right.
