However, most of our tunnel portals are stone type. I am not so sure in reality could notch a stone tunnel with a keystone in the center. Maybe we could flll the stone work with plaster and convert them to concrete style and notch them.

You can see them if you look closely driving the highway between Sunol and Niles.

In the future I was planning on running a longer train of various stack cars, and agree with you, that something should be done to the tunnel portals. "Notches" perhaps, like the prototype does. In fact, just like the Santa Fe did on Techeapi Pass for the SP.

I got a whole string of cars set up at Oildale (passenger track, Peter was running on the freight side), put some power on the front and headed towards the port. Coming out of the tunnel, by Grainger, it was noted that there was very little clearance between the top of the stacks and the tunnel portal. Clearance would have been better if I was on the freight side. Ran around the back and snagged a wire about a 1/3rd of the way along Hidden. Fixed that and continued the run under the city. Didn't check clearance at the other side, but no problems occured.. 1. Problem #1, tunnel portal not tall enough to clear stacks at Jamestown. Most missed, but one caught. Put the train back together, backed it down, switched over to the passenger track and continued up the layout. Still just barely cleared. 2. Problem #2. First tunnel entering summit seemed ok. Middle tunnels seemed ok. Tunnel exiting Summit not ok on either end. Something caught, midway, and string lined half the train. Front half was catching on bridge or just barely clearing. 3. Problem #3. Tunnel exiting the helix just barely clears. That was as far as we got with the train. By then, most cars were off the layout and back in boxes. We need some serious tunnel work if we want to run stack cars, and I think we should do it. Jere ran stacks on the Sunday of the train show and it appeared they made it around without problems. Go figure.
