The 4-6-0 "Ten Wheelers" produced at the park after the little 4-4-0 engines and were of a similar design. This detailed picture of one of these engines includes a group of the boy engineers used in those days to run the trains. A second crew member on each train was the conductor who had overall responsibility for the train and communicated to the engineer via a bell placed on the front of the first car. This bell was connected to the back of the end car by means of a rope which ran under the canopy of all the passenger cars in the train. The conductor used this bell from his base of operations at the back of the train to signal to the engineer at the front when to leave the station. The conductor's job included punching tickets which passengers purchased at the depot and making sure passengers were seated and bystanders out of the way when the train departed the station. The conductor was also responsible for signaling the roundhouse via an electric bell system when additional trains needed to be put into service based on the crowds waiting at the depots.
