On a 1:20 scale steam railroad?? Well, here is one thing that could be done. The new crane sitting in the evening sun at the Redding yards. The only thing used on the carrying car from the original crane are the trucks and the under frame. The car was scratched from Styrene and has 2 and 1/2 pound lead sheeting as the under deck to add weight to the car.
The “Brownhoist” lettering is vinyl stick on and the white lettering is decals made by Stan Cedarleaf. The new cab was scratched from Styrene
The original machine deck was used from the USA version but widened and lengthened to accomodate the boiler and tanks and operator deck in 1:20 scale. A new line tower was constructed from Styrene shapes and extended above the cab roof. The hole in the side of the cab is for the drum crank to raise and lower the boom.
The ratcheting pivot deck was cut from the USA car and transferred to the new scratch car to maintain the integrity of the pivoting motion.
Here you can see the slide out beams (below the car end beam) that act as stabilizers when the crane is in use. They would be pulled out and shored up with wood blocks and or jacks.
A little peek inside the cab. You can see the boiler and pressure gauge, the oil tank and some of the operating levers.
A close up of the car deck, you can see that the old concrete weight fill is cracking, probably won’t be long before weeds are growing from the cracks. Yes that was a lot of rivets to put in but who’s counting 
A comparsion shot of the two cranes, before and after you might say.
Another comparasion shot. The original boom was used without modification on the new crane except for paint and weathering.
Thanks for taking a look Rick
