Great Southern and Western Railway Notice sign

This is a no trespassing sign from the Great Southern and Western Railway. I know the picture quality isn't good, so I quote "Pursuant to section 90 of the Great Southern and Western Railway Act 1903 the public are hereby warned not trespass upon this railway. Persons found trespassing thereon will be prosecuted without further notice and will be liable to a penalty of forty shillings for each such offence. By order Francis B. Ormsby Secretary." I found out that this sign came from Ireland, and that Ormsby work for this railroad. Its made of cast iron and has little rust to it
