Speaking of big steam locomotives, the Henry Ford Museum has an H-8 class “Allegheny” engine on display. These were built to haul heavy trains of 160 coal cars, (each with a 60-ton load) over the steep grades of the Allegheny Mountains. (They probably hauled a few circus trains over the mountains, too.) Of the 60 Alleghenies that were built, only two still survive: this one #1601 at the Ford Museum, and #1604 at the Baltimore & Ohio Railroad Museum in Baltimore, Maryland. The Allegheny is 125-ft long, 11-ft 2-in wide, 16-ft 5 ½-in tall and weighs approximately 771,000-lbs. Its original cost was $230,663. Getting this locomotive into the museum’s main exhibition hall was a major undertaking.
