[Accrs-ho] Tunnel Portals

[ACCRS HO Scale]

That is true.   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.
