Adding Wood Chip Gondolas to the Roster



New Additions to the Layout

Woodchips are generated by lumber mills and separate purpose built woodchip mills in many areas of the U.S. and Canada. Most are used in paper or cardboard manufacture. While I have a paper mill on my layout, I chose not to model the wood chip portion due o space constraints.  Currently wood chips are received at the mill in the Yard and the loads removed after a set number of days before being returned to the yard as empty's.  Wood chips are received from either an off-site source, or from the Muskoka saw mill (on the layout).  As I discussed in another blog entry, I currently have four wood chip car resin kits manufactured by Alpine Railway Shops of Kettleby, Ontario, which were marketed as being representative of rolling stock used by CN and BCR for saw mills and paper mills. I have several additional car kits which are modeled after the BNSF cars to also handle chips.

A common variation of CP’s woodchip gondolas rebuilt from a 52′ gondola with extended sides.  Bill Grandin photo.

I recently found myself with three 52' gondola kits which I have tried to sell at several railroad shows, but unfortunately no takers. So rather then seeing them sit for months until the next show, I decided to try my hand at kitbashing these kits to resemble a photo I had seen of a CP rebuilt gondola that was placed into wood chip service. These would become lettered in the ONR, although to the best of my knowledge the ONR never had any cars that even approached this configuration.

From what I have been able to research, in the 1970's, CP Rail began to convert some randomly selected old boxcars to woodchip cars; this was done through the early 1980s.  These cars were made by cutting away the old roof and adding an extension. Later cars did not receive the extensions to the sides.  They also took an unknown number of 52' gondolas and extended the sides.

The story for my cars is that CP rebuilt these wood chip gondolas with extended sides from a standard gondola.  After some years of use in the north, CP parked them on a siding for lack of use.  The ONR then purchased them and repainted them to a woodchip only service marks that you see.

Adding bracing for wall extensions. I didn't like the looks of this so the other two cars were done by adding bar stock

No matter how carefully you cut, there are always gaps. Next step some sanding followed by painting

Finished gon in the progressive paint scheme and added Wood Chip Service Only. Note I carried all of the ribs forward on this car after realizing that the gon looked odd with only alternating ribs. Still need to make a load for this unit
