ENGLISH ELECTRIC TYPE 1
FRAME No. 1
GENERAL DESCRIPTION
This frame shows an ENGLISH ELECTRIC Type 1 diesel-electric locomotive.
The wheel arrangement is B-B; (i. e. the locomotive has two bogies, each of which has two individually-driven axles).
The locomotive may be operated singly, or may be coupled, to form a two-unit or a three-unit locomotive, with other locomotives which carry the 'blue star' coupling symbol.
An Old locomotive has, at the front and at the rear end, two red tail lights and four white marker lights. The marker lights have white marker discs. A New locomotive, however, has two red taillights and a route indicator at each end, but has no marker lights.
A New locomotive has automatic brake adjusters, which an Old locomotive has not.
