Data from the PLM Wiki vault crammed with data and plans at [], last accessed 3 November 2011. The plan comes from the 1869 PLM plan book collected by Roland Sermet. 1-9 were built by Robert Stephenson & Sons and the remainder by Louis Benet & Cie, all in 1846.
Typical passenger engine of the late 1840s with haystack firebox and short wheelbase.These had outside cylinders.
201 : Pierrot, 202 : Fauvette, 203 : Vautour, 204 : Milan, 205 : Condor, 206 : Aigle, 207 : Hirondelle, 208 : GoTland, 209 : Mouette, 210 : Martinet, 211 : Tarasque, 212 : Flamant, 213 : Faucon, 214 : Epervier, 215 : Pluvier, 216 : Engoulevent, 217 : Chastre, 218 : MTsange.
All but one of the locomotives was out of service by 1869.
NB: The boiler pressure setting is an estimate.

Interspersed among the haystack-boilered set of 2-2-2s (Locobase 13363) purchased by the A-M was this quintet of more modern looking locomotives. Stephenson supplied them with a single tall driver positioned just ahead of the firebox, a rigid supporting axle under the dome and just ahead of the drivers, and a third axle under the smokebox.
26 : Mistral, 27 : Trombe, 32 : Sacripant, 33 : Atalante, 40 : Norma
All but one of the locomotives was out of service by 1869.
NB: The boiler pressure setting is an estimate.
