Magnetic Signal Company Catalogue

Here are some highlights from the original Wigwag parts catalogue dated 1940.
Lots of great detail drawings and parts information. If you own or maintain a
Wigwag signal, these are quite useful.

This is part of the original catalogue put out by Magnetic Signal
Company. These were reproduced by former SP signal maintainer Jim Downard. Jim
has made more copies, so if you want one, email him. They are $15.

If you have any tech questions about wigwags, feel free to email Jim Downard.

Model 10 Type

This style was most commonly used on Santa Fe crossings. They normally mounted cross-bucks above the cantilever and
added "stop on red signal" or "stop when swinging" signs to them. Click here to see one of these in Emeryville Ca.
