620 Class 4-6-2 Pacifics

The 620 "Light Pacifics" were built to handle the heavy traffic on light 60lb rail branch lines throughout the state that could not be hauled by the heavy Webb era locomotives, necessitating the use of Rx class which on the other hand could not maintain the schedules. The first engine, 620, appeared in time for the centenary of South Australia's founding in 1936, although it appeared at the Centenary Exhibition slightly unfinished, being mounted on freight wagon bogies!

Their 60lb rail availability meant that they could go anywhere in the state, and their ready turn of speed meant that in spite of their general use on lighter branch lines, they even saw service on the Main South to Tailem Bend, hauling passenger trains. I can remember as a boy travelling on one or two such trains to Mount Lofty, and always thought them a great step up from the usual Rx!

621

621 has been preserved in operational state, and is now (Jul 1998) located on the Victor Harbour tourist line.

This line was isolated by the construction of the Adelaide-Melbourne standard gauge, effected by the gauge conversion of the existing broad gauge line.

    More from SA - in 1991 I think at the first Adelaide Grand Prix - a steam "race" out of the bizarre futuristic looking Adelaide station. These locos are 621, 520 and Rx207 - all of which you already have well documented on your website. Note the helicopter!
