French State Railway (État) 42-101 to 140

To increase their hauling power in suburban service from Paris Saint-Lazare, the État received 40 three-cylinder Mikado tank locomotives in 1932 and 1933. 20 each had been built by Schneider and Batignolles-Châtillon. They were inspired from the Est 141-701 to 141-742 (the later SNCF 141 TC) and had to enforce the two-cylinder 42-001 to 42-020 Mikado tanks. The new locomotives were numbered 42-101 to 42-140. In the SNCF they became 3-141 TD 101 to 140.

Their boiler had a Belpaire firebox with narrow grate and two arch tubes. The blast pipe was of the three-nozzle type and was later exchanged against the Kylchap type. They had a very good acceleration thanks to the combination of three cylinders and relatively small drivers of only 1,420 mm. From the start, they had push-pull controls to operate with Talbot coaches with a driving trailer. After passenger traffic had been taken over by electric trains on some lines, they also had to haul freight trains on electrified lines. The last steam train from Saint-Lazare was hauled by 141 TD 119 in February 1967.
