The MTH 20-6515 Seaboard 5 Car Streamliner set (Ribbed) is a highly detailed model train passenger car set designed for O gauge railroads. Made of plastic and diecast materials, the multicolor cars feature light function for added realism. This ready-to-go set is brand new, suitable for collectors and hobbyists aged 17 years and up. The streamlined design and 1:48 scale make it a great addition to any model railroad setup, especially for those who enjoy operating three-rail systems.
