Re: Wig-wag crossing signals on narrow gauge?

Here in California there are three, maybe four I can remember visiting in the last few years.

Pt Richmond. BNSF wanted to upgrade it but the city objected. See links below

Up the north coast near Willits, maybe it was Ukiah, the RR is not operating at all now, but the wigwag is still suspended overhead in an industrial area. Old NWP line, an SP subsidiary.

Roaring Camp & Big Trees, sorry the Standard Gauge that runs to Santa Cruz has one or two in Santa Cruz I noted when I rode their Christmas train last year.

The Pt Richmond wigwag info:

excerpted:
In the early 1900s, the Santa Fe railroad established a major rail yard adjacent to Point Richmond. The railroad constructed a tunnel through the Potrero San Pablo ridge to run a track from their yard to a ferry landing from which freight cars could be transshipped to San Francisco. Where this track crosses the main street in Point Richmond, there remain two of the last operational wigwag grade crossing signals in the United States, and the only surviving examples of the "upside-down" type. The wigwag is an antiquated type of railroad crossing signal which was phased out in the 1970s and 80s across the country. There was controversy in 2005 when the State Transportation Authority ordered the BNSF railroad company to upgrade the railroad crossing signs. A compromise was achieved that included installing new modern crossing equipment while not removing, but simply shutting off the historic ones and preserving their functionality for special events.[7]
