The Seatrain Puerto Rico formerly the T2-SE-A2 'Mission' lype tanker Mission San Luis Obispo, was
altered beyond recognition in 1967 at Newport News to a container and railway wagon earner for the
Hudson Waterways Corporation. Length was increased, superstructure relocated aft and a spar deck
equipped with twin 50-ton cranes was constructed. The fore end of the main deck was squared-off with
sponsons to match the shape of the spar deck above. Rail tracks are fitted in the lower deck and
vehicles/containers are carried on the main deck. The vessel operates under the colours of the as-
sociated Seatrain Lines of New Jersey. The Seatrain Carolina (ex Mission Santa Barbara) is a
similar conversion.
