Cast iron notice, Great Northern Railway, 'Public Warning not to trespass', white letters on black background

Trespassing on the railway has always been a serious offence. Warning signs in the earlier days of the railways were lengthy and explained the legal and financial implications of breaking the law.

This one reads:

Persons trespassing upon any Railways belonging or leased to or worked by the Great Northern Railway Company solely or in conjunction with any other Company or Companies, are liable to a penalty of Forty Shillings under the Great Northern Railway Act 1896, and in accordance with the provisions of the said Act public warning is hereby given to all persons not to trespass upon the said Railways. By Order. King's Cross, July 1896.
