French Western Railway No. 1011 to 1114
French State Railway 030 TA
France 1860 104 produced
In 1860, the Ouest had the first of these tank locomotives made as helpers on ramps. They had the wheel arrangement 0-6-0T and a firebox that overhung the coupled axles at the rear. The coal was carried in pockets in front of the footplate. After the suitability for shunting service became known, their number rose to 104. Some were built to haul freight trains on the Paris Ring and had larger water tanks. Over the years they were upgraded, for example with a cab. The SNCF took over 41 more in 1938 as 1-030 TA and 3-030 TA. In 1950 there were 29 left and the last disappeared in 1967.
