File:Turntable 04 - Baltimore and Ohio roundhouse Cleveland.jpg

English: A Cleveland, Terminal & Valley Railroad mail car on the turntable at the former Baltimore & Ohio Railroad roundhouse in Cleveland, Ohio, in the United States. The roundhouse was acquired by the Midwest Railway Preservation Society in 1954.

On the track behind it, in bright yellow and black, is Cuyahoga Valley Scenic Railroad locomotive 365. It was built between June 1963 and August 1968 by the American Locomotive Company (ALCO), as a Century 420 model. It had a B-B configuration (two trucks, each with two powered axles) and a 2,000 horsepower power plant. They were intended to be used as switchers.

It was originally Seaboard Air Line Railway locomotive number 124, and then Sea Coast Line locomotive number 1226. It was sold to the Louisville & Nashville (locomotive number 1365), and was owned by severl shortline railroads (including the Indiana Hi-Rail Corporation, where it received its current number). It was acquired by the CVSR in 2001. A generator went bad in 2010, and it was overhauled between 2013 and 2017, and went back into service in October 2017. The Ohio Locomotive Works removed the old engine and power plant and added an ECO LG 1550: A 162 hp John Deere unit for light loads, and a 1,560 hp, 16-cylinder MTU engine for heavy loads. This cut exhaust emissions by 98 percent and fuel use by 75 percent.

In the middle is a Trackmobile shunter. Behind it is Northern Illinois & Wisconsin Railway locomotive 1861. Built by GE Transportation Systems from 1988 to 1989, this is a Dash 8-40B model. It has a B-B configuration, and 4,000 hp (3,000 kW) power plant. It arrived at the MRPS in 2016 for refurbishment.

To the right is a Union Pacific caboose. Built in 1956, it was owned for many years by Ohio Northern Trucking and located at their business at 16120 Brookpark Road (hence the name and number on the side). It was donated to the MRPS in 2015 by the R.L. Wurz construction company.
