Muswellbrook Railway Station 150th anniversary celebrations, Fire and Rescue NSW Open Days, St Heliers Heavy Horse Field Days, Muswellbrook Heelers Memorial Day and Muswellbrook Greyhound Club's Cup Final provide a jam-packed weekend

A CENTURY and a half of proud history associated with NSW railways will be marked this weekend when the heritage-listed Muswellbrook Railway Station celebrates its 150th anniversary.

And, to commemorate the major milestone on Saturday, May 18, the day is expected to feature train rides, historical railway tours, music, markets and food stalls from 9am to 2pm.

A 620 Class2-car diesel train will be hard at work with free rides to and from Patterson, Maitland, Branxton and Singleton and from Muswellbrook to Denman throughout the day.

Entertainment will feature the Muswellbrook High School stage band and guitar ensemble, Mark the Barber, Shyanne Irwin, Brady Cavanagh and Laura and Sara.

Free activities include face painting and a jumping castle, classic car and miniature rail displays.

Coffee, food and market stalls will all be available, too.

The official opening includes the unveiling of a commemorative plaque at 11am by former Muswellbrook Shire mayor John Colvin.
