the first time on the NCC a start-to-stop booking of was required as only 31 minutes were allowed for the from Ballymena to Belfast. Two further coaches were built for the "North Atlantic Express" in 1935 and on arrival at Belfast in the morning the set was speedily attached to the Larne Harbour boat train to provide a through Portrush to Larne service. The "North Atlantic Express" was discontinued on the outbreak of World War Two although the coaches would be used on prestige services in the immediate post-war years. Railcars Four railcars entered service on the NCC's lines between 1933 and 1938. They were all double-ended single units with underfloor engines and running on two four-wheel bogies. The first of these, No.1, was long and seated 61 passengers. It had a traditionally constructed wooden body and was powered by two Leyland petrol engines with hydraulic transmission in the form of Lysholm-Smith torque converters. No.1 was re-engined with Leyland diesels in 1947 and again in 1959. The next car, No.2, introduced in 1934, was to a radically different design. An ungainly looking machine, it had a long, slab-sided lightweight body that was to prove problematic. To eliminate the need to run round its trailer at termini, it was equipped with an elevated driving position at each end (similar to some French railcars) so that the driver could see over the top of a trailer that was being propelled. No.2 could seat 75 third class and five first class passengers and was powered by two Leyland Diesel engines with a similar transmission to No.1. No.2's looks were improved somewhat when the raised drivers' cabs were removed during its NCC service. Railcars Nos.3 and 4 were built in 1935 and 1938 respectively and were virtually identical. Like No.2, they were long with elevated driving positions but there the similarity ended as the cars had "air smoothed" bodywork. Each seating 80 passengers, they too were powered by two Leyland Diesel engines with hydraulic transmission. In 1934, two railcar trailers emerged from York Road works. Of light weight construction, they weighed only 17 tons (17 tonne) but each could seat 100 passengers. They had a low roof profile so that the railcar driver in his elevated cab could more easily see ahead when propelling them.
