Making Your N Gauge Railway More Realistic

Book Description
Railway modelling offers a unique opportunity for the modeller to construct and operate an authentic simulation of the real thing. When one creates a model railway, one should strive to embed the sense of purpose from the real railway into their model. Simply moving trains around aimlessly around a layout may be enjoyable, but it doesn’t reflect how the real railway operates. There is much focus on absolute accuracy with regards to locomotives and rolling stock but far fewer modellers in general pay attention to prototypical accuracy and replicating authentic railway operations in miniature. Operating your layout in a realistic fashion is not only more authentic, but it can also be an enjoyable pastime in its own right. It gives purpose to the movement of every train on the layout and, if it involves co-operation between more than one operator, involves teamwork and good communication which can be immensely satisfying. Finally, realistic operation is supported by many other factors, a sense of time and setting, sensible track layout, correct placement of signals, the proper formation of trains, realistic civil engineering, and layout ‘clutter’. These all add to the overall atmosphere and setting of a real or fictional railway, tying it to a time and place, and making the whole ensemble more authentic and thus making the whole experience feel more ‘real’. This book is intended to help those with an interest in the BR Blue (TOPS) and Sectorisation eras present their layout in a realistic manner using easy-to-understand sketches and drawings, previously unpublished period photographs and source material from the era. This book will give the reader ideas to help their N Gauge model railway come to life.

British Railways in the 1970s and ’80s

British Railways in the 1970s and ’80s PDF Author: Greg Morse
Publisher: Bloomsbury Publishing
ISBN: 0747814104
Category : Transportation
Languages : en
Pages : 65

Book Description
For British Rail, the 1970s was a time of contrasts, when bad jokes about sandwiches and pork pies often belied real achievements, like increasing computerisation and the arrival of the high-speed Inter-City 125s. But while television advertisements told of an 'Age of the Train', Monday morning misery continued for many, the commuter experience steadily worsening as rolling stock aged and grew ever more uncomfortable. Even when BR launched new electrification schemes and new suburban trains in the 1980s, focus still fell on the problems that beset the Advanced Passenger Train, whose ignominious end came under full media glare. In British Railways in the 1970s and '80s, Greg Morse guides us through a world of Traveller's Fare, concrete concourses and peak-capped porters, a difficult period that began with the aftershock of Beeching but ended with BR becoming the first nationalised passenger network in the world to make a profit.
