After the Canadian Pacific Railway (CPR) discontinued its passenger service on September 25, 1976, the Historical Society moved the station by truck from the foot of Queen Street to the cloverleaf beside Rocky Point Park.

In 1986, the Port Moody Station Museum acquired the Venosta, a first-class CPR sleeper car.

Restoration of the railcar began in the fall of 1987, with volunteers from the Port Moody Heritage Society and the Westcoast Railway Association.

The garden, established in 2000 by curator Jim Millar, contains many examples of heritage and heirloom vegetables and flowers.

The concept is based on a tradition in the Galápagos, in which British whalers set up a post office barrel in 1793 on Floreana Island for passing ships to leave their unstamped mail for hand-delivery by others on their voyage home.
