Nice blog run by a signal maintainer

He only posted in August/July of last year, but this is a great blog. Thanks to Amy Coffin for referring this blog to me. This blog is run by a signal maintainer. He posted some posts of crossings, some of defect detectors, which are my two favorite things of railroads. Click here for the link. The blog is called "Photos from a Signal Maintainer", and it is run by Bill Cundiff.
