On30 Tunnel Portals

Are you in need of a tunnel portal or portals for your On30 layout? If so there are several options available -- either commercially available R-T-U (ready to use) or you can scratchbuild to meet your needs.

We have included some S Scale tunnel portals in the links above as some On30 modelers have decided on the use of S Scale tunnel portals for On30 layouts. Also please note that most if not all of the R-T-U tunnel portals still require stain/paint/weathering, and some are kits.

Scratchbuilding On30 Tunnel Portals

If you prefer to scratchbuild tunnel portal(s) you might consider these references:

There are also numerous magazine articles providing reference and how-to information for various types of tunnel portals. A few of them are listed below. For a more complete list visit the Trains.com Magazine Index - you will need a (free) account on Trains.com to use the index.
