DIESELPUNK- Streamline Steam
A very unlikely Streamliner was the Iraq State Railways PC Class as half it’s Bagdad -Mosul route was single track. They were built by Robert Stephenson and Hawthorns in 1941 to resemble British passenger express Pacifics, with a nose rounded like the LMS Coronation Class and valancing styled like the LNER Class A4.
They were still in service when I made my solitary railway journey from Bagdad but unfortunately my route was south to Shaibah rather than north to Mosul. The names of the stations en route to the south were thought provoking. Ur Junction (Ur of the Chaldees) and Babylon.
