PO-Midi 141-802, ex PO 5802. (PO works, Tours, 1914). First numbered 6201 and 6202, the 2 locomotives of this class were designed by E. Solacroup as heavy goods prototypes for "routes accidentées". 8 more were ordered, but the order was cancelled in WW 1. Both were reboilered in Perigueux works in 1935. To SNCF as 4 141 A 801 and 802.
The plan of these mikados were used in 1920 by Etat railway for 250 similar locos, and again in 1932 for 12 locos built in Poland for morrocan railways. No builder can be found in France  with the capacity to complete a large order, and the PO order more locos from the USA. Collection Jean-Pierre Vergez-Larrouy (jean-pierre.vergez@tele2.fr)
