This is the Nebrand and New Iceland Railway class H-1a, numbered 653. It was built by American Locomotive Company in 1937. It was used for excursion services and other jobs to do in Sandvia, and it was retired in 1979 and got on static display for a few years ago. As of 2018, the engineers paid a lot of money to restore the 653 into operating condition and it can run again for a few years too.
