Built as Lehigh & Hudson River 24 in December, 1965. It became Conrail 2074 in the 1976 merger, and became Maryland & Delaware 54 circa 1980, then became Arkansas & Missouri 54.
L&HR placed four orders for C420’s:
- L&HR 21-22 in June, 1963
- L&HR 23-24 in December, 1965
- L&HR 25-26 in January, 1966
- L&HR 27-29 in July, 1966
The Lehigh & Hudson River was a 90-mile bridge line between the Pennsylvania Railroad, Reading, Central Railroad of New Jersey, and Lehigh Valley and New England. It dieselized in 1950 with eleven RS3’s, adding two more the next year.
Facing the overhaul of the RS3’s in 1960, the C420’s allowed for unit reductions and increased speed, at a time when traffic was increasing.
Alco designed a new blue and gray paint scheme for the C420’s. The new units performed well and six more were bought using RS3’s as trade in credit. The first two units of this order, L&HR 23-24, were wreck while being delivered, and had to be returned to Alco to be rebuilt. They were issued new builder’s plates with a March, 1966, date.
