This design is adapted to camps where repairs to wood frames are more
readily made than forged parts, there being few forgings used. All
timber used in the construction of these trucks is straight-grain Red
Fir.

"Rainier" Logging Truck
We are the first builders of Logging Equipment to depart from the
practice of the last twenty years and produce a Logging Truck designed
along practical and economic lines. Modern railroading has developed
the "Cast Steel" Engine Frame, Tender Frame and Passenger Truck Frame.
Wherever safety is required together with lightness and durability,
Cast Steel has been introduced.
Following this modern plan we have constructed the "Rainier" All Cast
Steel Truck of eight pieces where ordinarily several hundred are used.
Each Side Frame is in one piece taking the place of Top Arch Bar,
Inverted Arch Bar, Tie Bar, Heel Brace, Truck Columns, and the many
Bolts used to hold these parts together.
Each End Frame is in one piece taking the place of Top End Bar, Bottom
End Bar, Striking Plate, Carry Iron, Corner Gussets, Brake Staff
Brackets, and the numerous Bolts necessary to tie these parts together.
The Draft Beams are each in one piece, taking the place of Draft
Timber, Draft Lugs, and the Bolts required to anchor them.
The use of Cast Steel permits of the most economic distribution of
the metal, and the "Rainier" Truck is an example of what can be
accomplished.
The Bolster and Bunk are similar to those used in the Hercules Trucks.
Springs are located under the Bolster to absorb shocks which would
otherwise be transferred directly to the Truck Frame. The Springs over
the Journal Boxes provide additional protection from shocks and also
permit the wheels to hold the rails on an uneven track or at low joints.
Brake Beams are hung between the wheels and kept high enough to protect
them in case of derailment.
The equipment includes Automatic Couplers to Couple with Standard
Equipment, 33 inches above rail, and 33 inch Chilled Cast Iron Wheels
fitted on Steel Axles with 5 × 9 inch Journals.
Journal Boxes are Malleable Iron. No Cast Iron is used with the
exception of Brake Shoes.
The Center Bearing of the Bunk and Bolster is so constructed that the
Bunk cannot turn over under load when train is started or stopped
suddenly, as the Bunk cannot be removed from the Truck until it is
turned parallel to the Draft Beams. The "Rainier" Truck stands for
safety first.
