Puffing Billy buys another Garratt
« on: January 19, 2012, 11:44:57 PM »
My friend Russell Hicks, a volunteer at the Puffing Billy Railway in Victoria, Australia, informs me that PBR has purchased another South African Railways Beyer-Garratt locomotive. NGG-16 No. 127 will join sister engine No. 129 in Australia sometime around mid-year. It will be loaded into three shipping containers for the voyage. Puffing Billy will have to regauge both engines from 24-inch to 30-inch gauge, but they have decided to use these two "foreign" engines to spare wear and tear on the native NA class 2-6-2T engines they've been using for 60 years. Preliminary work has already begun on No. 129 at the PBR shops.

Russ says of the NGG engines available, No. 127 was in the best condition. Puffing Billy also purchased half the spare parts available. Parts will be loaded into the water tanks on No. 127, which will then be welded shut. Two other engines, No, 139 and No. 156, were both inspected, but both were in poor condition. No. 156 is the last Garratt ever built. Both engines will probably be scrapped, along with a few other Garratts, also in poor condition, at other locations in South Africa.

Russell has sent me a drawing from South Africa that includes information about the axle-loadings of the NGG-16 engines. It's too large a document to include here, but if anyone wants it, send me an email and I'll forward it to you. He notes that the two-foot gauge lines in South Africa were mostly laid with 35-pound rail without tie plates, and the NGG engines had an average axle loading of 6.5 tons. By comparison, the NA-class 2-6-2T's at the Puffing Billy have a 7.5 ton axle loading and the other Garratt, G-42, is the big fellow with 9.5 tons per axle.

Thanks Wayne!

Yeah, its amazing how lightly such large locomotives can tread.  I seem to recall the NG15 2-8-2s have only a 7-ton axle loading as well.

As I recall, Linwood Moody stated that about the 3/5 of a Forney's weight is on the drivers.  That would mean the axle loading on each of B&SR #8's drivers would be about 10.5 tons.  But even that compares poorly with the 2' gauge Porter 0-4-0s at Jones & Laughlin Steel, which had axle loadings of 20 tons.

Best Regards,
