This is a Bachmann E-Z Track 90-Deg Crossing in HO scale (Part No. 160-44441). It features a steel alloy track with a black roadbed and comes 1 per card. The 90 Degree Crossing is very useful in various railroad designs. But if you want to create a 'Figure 8' layout, it's better to start with a 30 Degree Crossing.

Using this 90-degree crossing is easy. Just connect it to your existing E-Z Track according to your railroad design. When installing, make sure the track is well-aligned for smooth train movement. As for precautions, avoid placing heavy objects on the track to prevent deformation. For maintenance, regularly clean the track with a soft cloth to remove dust and debris. This will help keep your trains running smoothly on the track.
