There are several interesting parts to a wood built car and one of these is that it is not all wood. One of these important pieces of steel is the beam just below the window frame. It runs the complete length of the car and turns down at the ends of the car to help keep the ends from sagging by being bolted into the end frame just inside the corner post. There are also vertical rods that help stabilize the side of the body beside each window opening. There are also steel bolts that come up through the floor to hold the under car appliances like water tanks and battery boxes. These bolts have flat plates on the top ends which are bolted into the wood frame of the car.
The wood ribs of the clerestory are all bolted to both to the side frame of the car and to the main beam that holds up the upper part of the clerestory with 7/16 bolts. The lower ribs are also notched into the main beam of the clerestory for added strength. To my surprise the ribs that support both the lower and upper parts of the clerestory are made from 1 3/4" lumber and not 8/4 rough lumber as I first suspected. This will make it easy to replace these pieces as I can use standard off the shelf 2X6 or 2x8 fir lumber. If you look at the photo below there is a large timber that does not look to be running parallel to the rest. That is because it isn't. It is on an angle and runs from just under the windows at the centre of the car to the bottom frame member over the bolsters, This adds strength to the side of the car. More on this as I take more of the walls apart. |
This is the painted plywood on the lower clerestory ceiling.
The original colours are on the right (Smaller paint chips) and the work service colours (larger paint chips) are on the left. |
This is some of the Mahogany trim showing the work service colours painted over top of the clear shellac finish.

The drawing on the right is of the Pullman No.106 truck and is the closest drawing to the trucks on the 1090 I have found so far. These trucks are composite wood with steel plates for added support. There are literally hundreds of bolts holding these trucks together. Must have taken a carmen a long time to inspect these looking for possible broken parts. Each journal has a separate oval number plate attached to the side of the frame for ease of the carman referencing hot boxes and maintenance in his paperwork. They are numbered from 1 to 12, one for each wheel. |
