In the previous vid post there appears a very large loco. I thought this was a Big Boy but am now of the opinion it may be a Triplex owned by Larry Anderson.
Baldwin Locomotive Works built three 2-8-8-8-2 locomotives for the Erie Railroad between 1914 and 1916. One, #5014, was named “Matt H. Shay”. These engines rarely made a maximum speed of 10 miles per hour. The Erie Railroad scrapped their Triplexes in 1929, 1931, and 1933. One 2-8-8-8-4 was also built, for the Virginian Railway as # 700 in 1916. This was class XA, so named due to the experimental nature of the locomotive. The 2-8-8-8-4 was highly unsuccessful because of only making a maximum speed of 3–5 miles per hour and high maintenance costs. The XA was sent back to Baldwin Locomotive Works in 1920 to be converted to a 2-8-8-0 and a 2-8-2. These two engines were up in service until 1953. Neither of the two engines were preserved.
This is what one of the originals looked like:
This is a model of a Triplex made by MTH:
This vid is a ride behind Larry Anderson’s Triplex bur alas does not show the loco:
