PENRITH Library is hosting an exhibition to mark the 150th anniversary, with model trains, old photos, paintings by artist Phil Belbin, old paper railway tickets, ancient timetables, posters and even some railway dining-car cutlery.
"These paintings and model trains are on loan to us from Neil Cram," said Penrith's information librarian, Lorraine Stacker.
"The models are associated with Penrith railway station and the Blue Mountains, such as the T14 class locomotive, which hauled the original Fish train."
In the 19th century, the Fish was the only train which left the mountains for Sydney in the early morning and returned in the evening.
The train's steam-engine driver was named Jock Heron, so passengers came to call his train the Fish.
"Later on came the Chips, because that was the train which followed the Fish," Mrs Stacker said.
More train services later followed them and Fish and Chips fell out of common usage.
"They don't have those names any more but today's electric trains still run at those times. It still takes commuters home in the evening and takes them into Sydney the next morning."
The Penrith-Blue Mountains line carried trans-continental services to Western Australia, as it still does today. Posters from the 1950s and 1960s advertise restaurant car services and depict landscape presentations of central Australia, such as camels and other outback features.
The exhibition is open in the Penrith library until Tuesday, February 12.
