What is the difference between the scale and the gauge?

Which scales are the most popular?

See model trains in action this weekend, November 26-28, at the Model Railroad Show at the Science Museum of Virginia.

Answer:  A model railroad's scale is the model's measurement as a proportion of the original.  The gauge is the measurement between the rails of the track.

Watch the Sky Show: the Leonids

Want to wish upon a falling star? This is the week - the Leonid Meteor Shower peaks tomorrow. Earth is currently passing through the “tail” of Comet Tempel-Tuttle. Often called a “dirty snowball,” a comet usually orbits the sun in an elliptical orbit. The comet’s nucleus, consisting mostly of ice and dust, heats as it approaches the sun. Particles begin to stream out behind it and form the comet’s “tail.” As Earth passes through this “tail” the particles collide with the atmosphere and we see a meteor shower.

Question of the Week
