Class H-6e Mikado type locomotive (2-8-2) #639 is on display in Miller Park in Bloomington, IL. One of an order of thirty built by Lima in 1923 to haul freight (#632-#661), it was donated to the City of Bloomington by the New York, Chicago & St. Louis Railroad in 1959, having racked up some 3,000,000 miles on the road.
The NKP rostered one hundred and twenty-one Mikados delivered between 1917 and 1924. Sixty-six were built by Lima, thirty-five by Alco and fifteen by Baldwin, inherited from the Lake Erie & Western when it was taken over in 1923.
You can see one of NKP's earlier Mikado locomotives delivered in 1922 on the NKP H-6d #624 page of this website.
