Congratulations on the purchase of the Chicago and North 
Western E class Pacific, also nicknamed the “Yellow Jacket”.  
This O Scale prototype was built by ALCO’s Schenectady 
Works in September 1917 and ran for almost 40  years, after 
becoming renumbered in July 1956.  Because this 
locomotive is hand assembled with sheet and cast brass 
parts, please take care in handling the unit to prevent any 
accidental damage.

The locomotive package contains a replacement packet of 
screws, smoke fluid, traction tires (3-Rail models only), and a 
wrench for the side rods for your convenience.  Should you

need additional parts or service, contact our factory at the

Before You Use Your Engine:

The CN&W Yellow Jacket has been tested and greased 
before leaving the factory and is ready-to-run on any 0-54 
layout or larger.  However, it is recommended that all moving 
parts on this engine are lubricated lightly upon the first initial 
use and after a heavy or extended period of use, in order to 
enhance performance.  For specific lubrication points please 
refer to the diagram in Figure 1.

Maintaining Your Engine:

The engine and tender should be maintained periodically to 
insure proper operation and performance.  All moving parts 
should be oiled after 25 hours of operation.  On heavily used 
engines, bearing grease (or a similar lubricant) should be 
added to the gear box, located between the blind drivers on 
the drive train.  To add grease, remove the four small Phillips 
screws on the inspection cover and insert the grease using a 
screw driver.  For specific greasing points, please refer to the

diagram in Figure 2.  Reassemble and run the engine as 
normal.

Smoke Unit Instructions:

This engine is equipped with an operating smoke unit and is 
wired with an ON/OFF switch located under the cab directly 
behind the trailing truck.  If you decide not to use the smoke 
unit, then the ON/OFF switch should be in the OFF position.  
This step is highly recommended as the smoke unit will heat 
up and could eventually burn out.  To add fluid, simply pour 
about 10 drops of smoke fluid provided with your locomotive, 
into the smoke stack.  After adding the smoke fluid, apply 
power to your track and after several seconds the engine will 
begin to smoke.

Battery Installation Instructions For Conventional 
Mode:

To operate this engine successfully in conventional mode, a 
9 volt battery needs to be installed in your tender.  There are 
four 3mm screws, one on each corner of the tender floor.  To 
install your battery, remove the four screws from the bottom 
of the tender and the tender shell will then remove easily.  
You will find a 9 volt battery connector end wrapped in black 
electrical tape among the wires.  Install the battery, place the 
tender shell back on the tender floor, and reinstall the four 
3mm screws.

Sound System Operating Instructions (This 
Section Applies Only To 3-Rail Locomotives With 
Sound):

All our 3-Rail with sound engines are equipped with 
Railsounds™ the finest sound system available today and 
the industry's premier digital operating control system, 
TrainMaster® Command Control.  This system will operate 
with a conventional transformer but the additional sound
