For this purpose the Blonay–Chamby Railway built two motive power and carriage depots at Chaulin, a short distance from its upper terminus.

They house what is generally regarded as the largest and most representative collection of preservation metre gauge rolling stock in the world.

Vintage steam and electric hauled trains depart from Blonay and climb slowly through a spectacular environment with fine views over Lake Geneva and the Alps.

After reversing at or just before Chamby, the trains terminate at the museum site, where visitors can explore stationary exhibits.

A further part of the remit of the preservation group is the encouragement of local and regional tourism and tourist traffic on adjacent lines.
