No. 170 as it appears on static display

Nickel Plate Road (NKP) No. 170 is a Class L1a a type of 4-6-4 "Hudson" steam locomotive. It was built in 1927 by Alco for the Nickel Plate Road.

This special Hudson was used to haul heavy passenger trains on the Nickel Plate Road railroad.

The locomotive was also used for freight service.

No. 170 remained in service until 1947 when passenger trains on the Nickel Plate were taken over by diesels, but the locomotive continued in freight service for some years.

The locomotive is now a public display at the St. Louis Museum of Transportation.


No. 170 is the only remaining Hudson for the Nickel Plate Road.

It was only the second Hudson type locomotive built.

It is the sole surviving Nickel Plate Hudson, and was donated to the museum by the railroad in 1957.

No. 170 is the only surviving example of a Hudson with Smoke Deflectors.

Outshopped by Alco in February 1927, about a month before NKP #170, the locomotive design was developed and perfected by the NYC, which eventually rostered two hundred and seventy-five of the type.
