Typical
of hundreds of facilities throughout the US, the Dolores, Colorado,
CONOCO Oil Plant was constructed prior to 1916 and lasted at least
until the end of the
Rio Grande
Southern (RGS) railroad in 1951. Served by a narrow gauge siding,
the facility works equally well on standard gauge railroads as a
destination for tank cars or box cars (carrying cases and drums of
petroleum products). CONOCO was the west's largest petroleum
company and continues today after merging with the Phillips Corporation
in 2002.
It
actually took several years and the efforts of some very dedicated
modelers to produce this special kit. Finding a method to
mass produce historically accurate bulk oil tanks was the largest
hurdle. In the end, special software was used to generate files
allowing Rapid Prototyping equipment to produce wrappers for the tank
masters. But more was needed. The tank ends, as well as the
access hatch covers required that molds be milled for injection
casting. Special injection molds for the filler pipes were also
made and masters were made for accurately casting the chimney and tanks in
resin.
A lot of problems had to be solved along the way!
The
kit consists of four structures: The Office has a tar paper roof
(peel-and-stick) and is made using scribed, or "drop"
siding. In HO it only measures 2 x 1¾-inches deep (S:
2¼ x 2¾). The
garage (HO: 1½ x 2¼-inches; S: 1¾
x 3), uses the
prototype's
corrugated siding for the sides and roof, and the doors can be mounted
either open or closed. The large warehouse (HO: 3 x 5-inches
long; S: 4 x 6¾) contains three large doors that can be mounted
open or closed and also uses corrugated material for the siding and
roof.
The Small Warehouse is probably the original structure from when the
facility was
first built (HO: 2 x 2½-inches;
S: 2¾
x 3¼) and has a small extension on one wall that serves as
a transfer pump
house. It, too, uses the corrugated material. A full roll
of
Ragg's Sticky Tape is included in each kit to apply the
corrugated material.
The
kit includes the four storage tanks, two of each size, as the
prototype. They rest on "concrete" saddles, made from
Northeastern's special Concrete Form Board, lightly showing the forms
used to shape the saddles. The kits include several jigs to
aid in assembly, including one to help locate the tanks and the piping.
The piping, included, is made
from
either special injection molded parts or brass rod and castings
(Precision Scale
Company). Extra pipe supports are included should you decide to
modify the routing of the plumbing. Three special pipes are
included (see above photo) to simulate the hose connections with your
tank cars into the pump house.
The large platform includes the
stairway at one end and the ramp at the other. It's designed to
allow a certain amount of reconfiguring for other arrangements of the
structures. (An extra stairway is included.) The basswood decking is peel-and-stick, made in
large, pre-cut pieces. If the
platform, two warehouses, and four tanks are prototypically arranged,
they measure 15½-inches long x 6¼-inches deep in HO and
20 x 8¼-inches
in S. The
Office and Garage can be located as shown, but are not included in
these
measurements.
I recently added the CONOCO plant to my own version of Dolores. As you can see by the photos below, my space was somewhat irregular and limited. Because of the yard located immediately behind the facility it was necessary to separate the two warehouses and to build the tanks and pump house as mirror images. This was a bit of a challenge but not impossible!
