This image shows the wood-fired narrow gauge steam locomotive that provided tourists an opportunity to travel around the park by train. The operation is called the Ghost Town and Calico Railway.

The description on the back is written in the form of a personal message:
THE GHOST TOWN AND CALICO RAILROAD
MEETING THE STAGE COACH
Ghost Town, Knott’s Berry Farm
Buena Park, California
As an extra treat during out memorable visit in Ghost Town we enjoyed a ride on this famous old narrow-gauge Train, formerly noted as the Denver Rio Grande. Talking about excitement – during the trip two hold-up men boarded the train and nearly scared the wits out of the passengers. We also rode in an authentic Stage Coach through the shady grounds surrounding Ghost Town.
–The locomotive has a passing resemblance to the famous 4-4-0 American type, but in this case the engine is a 2-8-0 Consolidation. The train service began in 1951, and the card likely dates from a short time after that.
