About Us

Mercer JunctionMercer Junction is located in beautiful, historic Mercer Pennsylvania.
We specialize in O Scale trains and accessories. Our three major manufacturers are Mike’s Train House, Lionel and Atlas .Products from these manufacturers range from starter sets to highly detailed, scale, handmade brass engines and rolling stock. We also stock a full line of scenery supplies, track, switches, scented smoke and O scale figures.

One of our most spectacular features is the 21’x10’ in store layout. It is used to demonstrate the DCS operating system and allows customers to run their newly purchased trains and give potential modelers an idea of what they can achieve.
Mercer Junction is not only a retail train store but, more importantly, a destination and source for comradery and learning for the O scale community.
