By this time, Morgan himself, whose transportation business was steadily expanding, had become the plant's main customer. In 1850, Morgan ordered the 1,875 ton steamer "San Francisco" and the 1,359 ton "Brother Jonathan", both built for operation with Morgan's Empire City Line. In 1852, he decided to replace some of his older ships, and ordered "Texas" (1,151 tons), "Louisiana" (1,056 t), "Mexico" (1,043 t), "Perseverance" (827 t) and "Meteor" (542 t) all of which had engines built by the Morgan Iron Works.
