This year marks the 150th anniversary of the opening of the Penrith train station and this important milestone in Penrith's history is being celebrated at the library.
An exhibition, The Day the Train Came to Penrith, is in the research room until February 12.
It features five replica model trains from the 1860s, original paintings of local trains, train dining-service silverware and cutlery and the pocket watch of John "Jock" Heron - one of the first train drivers on the western line.
Memorabilia from several of the early train drivers is also on show in one of the library's glass cabinets.
Along with photos of the original station and trains, there are also ticket stubs and a train driver's journal.
The exhibition was co-ordinated by Penrith Council's historian, Lorraine Stacker, who said the opening of the station had such an enormous impact on the city and its residents that it was important to acknowledge its 150th anniversary.
"The coming of the railway meant employment and economic security, full schools and viable retail and commercial businesses for Penrith," she said.
"It was also the beginning of tourism - easy access to the broad expanses of the river, the beauty spots of Mulgoa and Wallacia and the ever-popular swimming spots at "Little Manly" at Emu Plains.
"The train also meant a much easier and quicker travel into Sydney for commuters and the movement of produce to Sydney markets.
"Interestingly, a train trip then was not much longer than an express trip today!"
