I think it is unlikely that 150P13 will ever run again. It is the sole survivor of its class and in effect is a national historic asset. Almost none of the locomotives at Mulhouse or seconded from Mulhouse have ever been restored to working order - they are strictly static exhibits, and some - like the 230D - may be missing crucial parts. Also the money necessary to pay for a return to working order just is not available. There will inevitably come a time when these engines are considered too fragile to restore.
