[b_thom at juno.com]

Two circus trains will be in or near DC tomorrow. One will be headed
north from Richmond going to New Jersey. The other will coming from the
west going to Baltimore. That second train may go through Mt. Airy and
Sykesville, or it may go through Gaithersburg, Silver Spring, and Laurel.

On the radio, they'll sound like all the other trains, but they are
something different.
