Interesting. It is artist's licence, though. British stock would certainly fit within the average Euro loading gauge and a small number of engines have visited some of the steam festivals over there, including a Small Prairie which worked regular services over the Wolsztyn route in Poland.

Having said that, I think there might be a near-precedent for the artwork though, because I seem to recall "Britannia" visiting Carnforth in the preservation era whilst the late Dr. Beet's DB 01.10 Pacific 01.1104 was kept there. The latter only steamed occasionally within the confines of the yard since it exceeded the BR loading gauge by some margin. Without looking at the 01.10 drawings, I think the width over cylinders worked out at something over 10ft, whilst the height was around 13ft 6in-plus.

Don't forget also that, roundabout the time when the Waverley Route was closed, there was a plan to reopen some of it and run services using ex-DB engines. This idea died when someone remembered that the loading gauge and clearances were too small for the Germans!

Thanks for the above comments. I think the illustration (which can be downloaded as a pdf) is meant to be historic, so probably 1950's to 1960's. There were frequent West Coast diversions for electrification works around that time but Leipzig ?

The intriguing question is why Trix / Marklin opted to use that historically inaccurate picture containing a BR loco as a setting for the Br03 in their new catalogue.
