The German children's train has carriages in the two-tone, chocolate brown and cream livery of the Great Western Railway, yet Liverpool Street was a terminus of the London & North-Eastern Railway which had a one-tone teak livery for its carriages.
It was customary for the host and hostess to sit in the middle of the dining table, not the ends as seen here. This enabled conversation with all guests easily.
The engine pulling the German children's train has no insignia, yet all London & North Eastern Railway engines had "L N E R" proudly painted along their boilers in finely detailed letters, often over a foot high, until the outbreak of war.
