During 1831-35 the company's shops were located at Hoboken, N.J., and
during the winter of 1832-33, three locomotives were commenced at
these shops (two completed before March, 1833, the other in April),
the valves, cylinders, pistons, etc., coming from England, the boilers
being made under the direction of Robert L. Stevens. It was his
opinion that the "John Bull" was too heavy, and the new boilers were
built smaller and lighter, so that the engines, when completed,
weighed eight instead of ten tons. With these three engines, which
were delivered to the railroad company at South Amboy, the stone
blocks and other material for the permanent track was delivered along
the line of the road.
