D&RGW K-28 COAL FIRED MANUAL

4

FIRING

Firing and running a coal fired locomotive is an entirely different experience from that of a butane fired engine. 

Coal firing is a dynamic process that is continuously changing from moment to moment. The variables presented 

by temperature, humidity, track conditions, train load, firing technique, distractions and your attention to the firing 

process will make every run a new and challenging event. Although many of the elements of running your locomo-

tive will be familiar to you from running a butane fired locomotive, coal firing introduces many new elements that 

require you to be continuously thoughtful and attentive .

Unlike a butane fired locomotive, you can not set your coal fired K•28 running down the track while you casually 

stand by watching it perform or visit with onlookers; it needs your constant attention. Many butane locomotives 

will run out of fuel before water, and slowly come to a stop with no harm done. The functioning water level of a 

butane locomotive, with its usual single flue, located along the bottom of the boiler, is less critical than that of a 

coal fired boiler with a crown sheet. The crown sheet needs to be in constant contact with water to keep from be

-

ing permanently damaged. This means you must devote yourself to being ever watchful of the water gauge. The 

combustion of coal is also a more intricate process than the burning of butane. Coal firing needs to be managed 

in a thoughtful manner; the regular stoking and proper management of the firebox is an absolute necessity to a 

successful run. Stoking the firebox, like maintaining water level , can not be done in a haphazard manner.

The various elements of owning and firing your coal fired conversion are thoroughly covered in the five sections of 

this manual.

 

Section 1 - Materials Needed

 

Section 2 - Instructions

 

Section 3 - Owner Maintenance

 

Section 4 - Attachments

 

Section 5 - Firing Checklist and Quick Reference

 

One laminated for trackside use.

All of these materials are provided to assist you in getting the most out of your Coal Fired K-28, and we hope 

every run will be an enjoyable one.
