The train in the picture ran via Delsberg to Basel, but came from Brig as IR 51. Its formation is 
typical 
of that time and carried the express train carriages D EW II, 2 A EW IV and 4 B EW II on the line 
Brig-Lausanne-Biel-Basel/Zürich-Romanshorn (hourly service, Brig-Lausanne not hourly service and 
Brig-Sion 
as a regional train).
The number of A EW IVs made it possible to equip 1st class long-distance express trains with modern 
carriages. In contrast, 2nd class still had to make do with only slightly modernized EW IIs 
("comfort strips", referred to internally as B(r)). Re 4/4 IIs usually pulled these trains. However, 
it was not 
uncommon for these locomotives to be replaced by Re 460s. Depending on the time of day 
and the route, reinforcement cars (usually 1 or 2 B EW I, if necessary for the Zurich area 
also an additional A EW I) and 1-2 Z or Z2 were coupled to side D or side B of the train, depending 
on the operational advantage.
