Thought I would like to build a model of a Garratt locomotive next so I went searching for some photos of them on the internet.
Being mostly ignorant of equipment used on railroads in foreign countries, I had thought that this type of locomotive was only used in Great Britain and that they only made one style of this locomotive.
Boy .. was I in for a surprise .....
I quickly realized that the Beyer-Garratt steam locomotive was used all over Europe and some of them are still in regular use in Australia and Africa.
They were built as small as a wheel arrangement of 0-4-0 + 0-4-0 all the way up to 4-8-2 + 2-8-4.
Here are a few photos starting with the smaller locomotives and going to the bigger ones.
They also show up in a variety of colors.
Some photos of a couple of the locomotive that are still in operation.
SO .... after spending some time looking at photos of them and seeing some of them running on Youtube, I started digging up parts to start building my model and this is what I have to start with.
These are parts of two European 0-6-0 locomotives that are plastic models made by Pola Maxi in Germany.
They are suppose to look like this but my two models have seen better days.
I'm going to build a 0-6-0 + 0-6-0 so I stripped the two models down to the basic chassis by removing the side rods and valve linkage and the steam cylinders.
The steam cylinders are the wrong design and the side rods and valve linkage are all plastic so I'm not going to use these parts.
The Garratt locomotive has a front and rear set of drive wheels with the water tank sitting over the front set of wheels and the coal tender is over the rear set of wheels.
The boiler is mounted on a carriage frame work that is hung between the two sets of drive wheels.
Each set of drive wheels has the steam cylinders at the far end of the chassis and it pivots at the other end where the boiler is mounted over the end set of wheels.
The first problem that I see is the electric motors on the plastic models is in the cab with the steam cylinders at the front.
I can't make the pivot mount for the boiler carriage on the opposite end from the cylinders because the electric motors are there.
So I need to mount the steam cylinders on the end with the electric motor so it will be hidden inside the water tank and the coal tender and the carriage for the boiler can then pivot on the other end of the two chassis units.
( Whew ... I hope that wasn't too confusing ? )
Back to my old standby of parts for building plastic locomotives, I'm milling the top off a steam cylinder from the Rivarossi 0-8-0 locomotive kit.
The tops are milled off both steam cylinders and I'm gluing a piece of styrene on top of them.
The individual parts are shown in the foreground and the piece of styrene is clamped onto the cylinder in the back ground, waiting for the glue to dry.
The next problem is the plastic models have the center drive wheels connected to the steam cylinders and the Garratt locomotives have the far end drive wheels connected to the steam cylinders so I need to switch the wheels.
The crank pin and eccentric lever are made from plastic on the model so I have to make new crank pins out of steel rod for the rear drive wheels.
The steel crank pins are made up and pressed into the drive wheels.
The center wheels and the end wheels have been switched and the crank pins are pressed into the end drive wheels.
The other two pairs of wheels have the crank pin hole threaded so I can screw a small shoulder screw into them to hold the side rods in place.
So far .. I have a pair of 0-6-0 chassis units, steam cylinders that will fit them now, brass valve linkage ( That I think I can make work ) and the main rods for the steam cylinders.
I wasn't able to find any side rods in my parts that will fit the wheel spread on these two chassis.
So I'm going to machine the side rods out of some strips of brass.
The side rods are finished and mounted on the two chassis.
The steam cylinder is mounted on the end of the chassis with two small screws and the electric motor is set in place.
The main rod is set into the guides on the cylinders and on the crank pin to see how everything fits.
