The Erie's second group of 2-8-4s came from Lima Locomotive Works in 1927. In common with all the Erie Berkshires, these members of the S-2 class had 28½x32-inch cylinders. However, they sustained 250 p.s.i. of boiler pressure, whereas the earlier group had a pressure of 225 p.s.i. As a result their tractive effort was 78,904 pounds compared with 71,014 pounds for the S-1 class. Additionally, their engine weight was 457,500 pounds, 14,000 pounds greater than the earlier group. For other specifications see the commentary for No. 3384. This image of No. 3329 was snapped at Hammond, Indiana, in August 1950 and was part of the collection of the late Harold Vollrath. However, it was taken from a discontinued Flickr site and also appears in the ABPR Archive.
