This 4-piece set of 18-inch radius curved track from Bachmann's E-Z Track system is in HO scale (product code 160-44401). The track is made of steel alloy with a black roadbed and comes bulk packed, 4 pieces per card. The 18-inch radius curve is the basic curve of the E-Z Track system. You can place it inside a 22-inch radius curved E-Z Track for a more realistic double - track mainline. Four pieces of this track form one - third (120 degrees) of a 36 - inch diameter circle, adding great flexibility to your model railway layout.

Using this track is easy. First, find a flat surface for your model railway layout. Then, take the track pieces out of the card. Connect the 4 pieces together to form a 120 - degree curve. If you want a double - track mainline, place this 18 - inch radius track inside a 22 - inch radius E - Z Track. When handling the track, be careful not to bend it too much as it's made of steel alloy. For maintenance, use a soft, dry cloth to wipe off any dust regularly. If there's dirt, you can use a mild cleaner, but make sure to dry it thoroughly afterwards. This will keep your track in good condition and ensure smooth running of your model trains.
