Nobelius Siding is situated on the Puffing Billy Railway in Emerald. The siding was built in 1904 to service the adjacent packing shed built the same year. The siding was originally used to load rail trucks with Nursery seedlings and plants for the C.A. Nobelius' Gembrook Nursery for shipment throughout Australia. The Nobelius nursery was once the largest plant nursery in the Southern Hemisphere with 200,000 trees grown on 180 hectares.
The Packing Shed has been restored by Puffing Billy Volunteers and is now used by the Railway as a function centre, mainly in association with the evening Dinner Trains which run on most Friday and Saturday evenings (plus other selected evenings) from Belgrave to Nobelius Siding, where passengers disembark and enjoy a 3-course meal inside the Packing Shed before returning on the train to Belgrave.
