About Us

Mercer JunctionMercer Junction is located in beautiful, historic Mercer Pennsylvania on North Diamond street, right across from the courthouse.
We specialize in O Scale trains and accessories. Our four major manufacturers are Mike’s Train House, Lionel, Atlas and 3rd Rail. 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.
We host a variety of in house classes on various topics, such as: DCS operation, wiring, scenery, scratch building structures and custom painting.

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.
