Oops, I looked again and read the fine print. It says couplers and clamshell bucket not included. But for another $16.95 (taxes, tags, destination fee, and dealer added options not included), you can get the bucket from Walthers: http://www.walthers.com/exec/productinfo/247-7282
If your talking scrap yard you may want to consider a magnet rather then a clam shell for your overhead crane. Magnets would be more efficient in picking up scrap and loading it in to gondola’s
here is a crane that is DCC and made by ROCO. It is compatible with the Marklin system, but I am sure it can be converted to Digitrax or something similar. Maybe some of the modelers from Germany can give us some advice as well.
Also it comes with a clam shell bucket that operates properly and a magnet can also be added. Also Marklin makes cranes that operate and can have a bucket, or magnet attached. It is no longer available, but many of them can be purchased at train shows and ebay.
I know of an “OO” scale over the track crane that might work for you. It was originally madeby Airfix and is now made by Dapol, both model companies in England. I am right now building a through-girder turntable using the parts from a turntable kit that Dapol makes. Thanks!
Dapol had the kit in stock. Thanks for the tip. I just recieved it today. Now I just have to get it to the workbench to put it together. I saw this crane on two other club layouts. They look great.
