Tramways Monthly--A New Online Magazine ~ Thursday, March 05, 2009
Visit http://203.122.240.118/tmonthly (no domain name, apparently) to download current (#2) and back issues in PDF format, and/or subscribe to get future issues by email.
The coverage is international but seems to be UK-centered.
You could read this online, or since each issue is a PDF, if you have a color printer and don't mind blowing through a lot of color ink <cough>print it at work</cough> you could read it like a physical magazine.
