railway transport was severely disrupted by The Emergency. Lack of high quality coal fuel in Ireland and the need to import from England was severe and desperate alternatives such as turf-burning had only extremely limited success. By 1944 most non-suburban passenger services were restricted to Mondays and Thursdays only with some curtailed altogether. Transfer to CIÉ The Transport Act 1944 dissolved the company and transferred its assets, together with those of the Dublin United Transport Company to Córas Iompair Éireann, from 1 January 1945. Route network Over the period of the GSR's existence the total route network was reduced slightly from in 1925 to at the end in 1944. Among the few lines closed in the intervening years were the former Midland Great Western lines from Galway to Clifden (in 1935) and from Westport to Achill (in 1937). The stretch of line that was double track was reduced more significantly, from to in the same period. Locomotives and rolling stock Locomotives A wide variety of locomotives and rolling stock was inherited from the constituent companies. 1925 records show 526 broad and 41 narrow gauge steam locomotives remaining inherited from the originating companies. Locomotives were renumbered into the GSR class number scheme whereby the lowest numbered engine in the class was used as the class identity. There was a parallel Inchicore scheme that used a letter to indicate the axle layout and a number to designate different groups within the class. When the GSR passed into CIÉ at the end of 1944 the total number of broad gauge steam locomotives was about 475 of which 58 had been built by GSR. About 28 narrow gauge steam locomotives remained. Rolling stock The total number of passenger vehicles including post office, parcel, and brakes vans was 1670 in 1925, falling to 1337 by 1944. Railcars The GSR introduced four Sentinel steam railcars in 1928 with the power unit similar to the GSR Class 280, operating range of over and a passenger capacity for 55. All were withdrawn in the early 1940s. A subsequent order from Claytons in 1928 were less successful and withdrawn in 1932, a model exists in the Fry railway collection. Four Drewry petrol powered railcars of which two were narrow gauge were also introduced around 1927, with all four also being withdrawn by the mid 1940s. The innovative Drumm Battery Train was successfully operated on the Dublin—Bray route from 1932.
