This 44507 Bachmann / E-Z Track NS track set comes with five pieces of HO scale curved track. These five pieces form one - quarter (90 degrees) of a 71 - inch diameter circle. The 35.5 - inch radius curved track is ideal for creating wide, smooth railroad curves. It can easily accommodate longer locomotives and rolling stock, allowing mainline trains to run at higher speeds. Place it outside a 33.25 - inch radius curved track for a realistic double - track mainline look. It's also great for quickly laying track on a behind - the - scenes helix.

Using this track set is easy. First, find a flat surface where you want to set up your railroad. Arrange the five pieces of track to form the 90 - degree curve as they are designed. If you're making a double - track mainline, place this 35.5 - inch radius track outside the 33.25 - inch radius track. For a helix, you can quickly lay this track to get it up and running. When it comes to maintenance, keep the track clean from dust and debris regularly. You can use a soft brush to gently clean the surface. Also, check the connections between the track pieces to make sure they are secure. Avoid bending or twisting the track too much as it may damage the shape and affect the performance of your trains.
