*REVISED in 2011*

A technical look at Deltic locomotives.

Includes invaluable reference data for Deltic modellers


DELTIC DE-MYTHOLOGY front cover

This publication provides both technical reference data and articles explaining some of the mysteries of how a Deltic loco works. Also included is a technical history of the Deltic diesel engine, plus invaluable data and dimensions for model makers (chapters 3 and 4).

2011 REVISION: This is mainly the addition of body dimension data for modellers, added to chapter 4.


Chapter 1 "FREQUENTLY ASKED TECHNICAL QUESTIONS & THEIR ANSWERS"

A beginners' guide to the basic layout of a Deltic and also answers to some questions that often arise. From telling one end of a loco from the other, to why sparks fly out of the exhausts.

Chapter 2 "LOAD REGULATION/CONTROL & ELECTRIC TRANSMISSION - HOW IT WORKS"

A look at the theory of how the power of a Deltic is controlled and transmitted to the wheels. The governors, transmission circuit, load regulators, wheel-slip circuits, etc. are covered. Be warned that the explanation of how the governor works is rather involved!

Chapter 3 "DELTIC FIDELITY"

Reference data for Deltic modellers. This covers detail modifications and variations found on the Deltic fleet during their BR careers. This should assist modellers who wish to make sure that every detail is correct for the period and loco that they are depicting.

***

Many of the details described are illustrated with line drawings. There are also 3 pages of small colour photos (plus an artist sketch and a computer image) to clarify some of the points covered. Note that this chapter is not fully comprehensive for the dates when each loco received each modification. For the better documented mods (e.g. most livery changes, ETH, dual-braking, headcode blanking), precise dates are given for each loco. For many other changes, only an approximate guide is given, based upon photo evidence. However, this chapter highlights a great many details not widely known.

These include changes to: Fan mesh, boiler roof, cab windows, buffers, axle-boxes, livery details and much more.

This 2011 revision includes a computer generated image to illustrate the long lost outer sand boxes and original buffer cowls.

Chapter 4 "TECHNICAL DATA"

Technical reference data for the production Deltic locos, more extensive than that usually seen in print, and also conflicting with some figures in general circulation. Even the overall length of the loco is wrongly quoted almost everywhere! Explanatory notes are included where appropriate.

This 2011 revised version now includes invaluable data for modellers. Dimensions of the body including radii of curves, details of nose dimensions, and even measurements for long lost fittings.

Chapter 5 "PROBABLY THE BEST ENGINE IN THE WORLD"

The story of the Deltic diesel engine's origins and also explaining the mysteries of how these diesels achieved such high power.

From stationary engines in 1890s Germany, to Junkers aero-engines in the 1930s. Development and technical details of series 1 and 2 Deltic diesel engines. How it achieved high power and low weight, unlike conventional diesel engines. Why it did not become more widely used. The merits of the Prototype Deltic loco's bogie design.
