Typical
of hundreds of facilities throughout the US, the Dolores, Colorado,
CONOCO Bulk 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 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 "drop
siding". In HO it only measures 2 x 1¾-inches deep (S:
2¼ x 2¾;
O:
3 x
3½). The
garage (HO: 1½ x 2¼-inches; S: 1¾
x 3; O:
2½ x 4), 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;
O:
5¼ x 9) 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;
O:
3½ x 4) and has a small extension on one wall that serves as
a pump
house. It, too, uses the corrugated material. A full roll
of
extra tacky, double-stick 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 and center the pipes
exiting the tanks. (Although the Jordan tank truck is not
included in the kit, decals for the "Continental Oil Company" sign are.)

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. 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;
20 x 8¼-inches
in S; and, 26¾ x 11-inches in
O. The
Office and Garage can be located as shown, but are not included in
these
measurements.
