My vector drawing (no auto trace) of the classic steam locomotive Flying Scotsman, fitted with blinkers.
No image may be reproduced, copied, edited, published, or uploaded without my permission.
The original flying Scotsman had a single chimney and did not require blinkers but, when a double chimney was fitted to increase the efficiency of the engine, it was found that blinkers had to be fitted to prevent the driver from being blinded by smoke.
When I was young I lived in a village near Doncaster, in Yorkshire, that was a train spotters dream and during the steam era, every young boy was a train spotter and dreamed of being a train driver.
