Having watched this cab ride video on You Tube, when at 3.15 the
train enters Switzerland, I'd like to ask why the catenary is of
German type until the border, with the signalling changing near but
not at the border. https://youtu.be/u5ZmrTJs47Q?t=195. Is this
historical due to the builder of the railway, or for some other
reason. At most country borders, but not all by any means, the
catenary usually changes at the border and the signalling at the
station at which most loco changes (if any) are made.
The train doesn't enter Switzerland at 3:15. The railway border is earlier than the road border. See

And the situation around Basel is quite complicated, because, thanks to a common voltage, there is not a single point of change. There is rather a border area, which has been defined in official contracts between Germany and Switzerland. These are the so called "Grenzbetriebsstrecken" which allow a locomotive approved for Germany to reach Muttenz and Basel SBB and allow a locomotive approved for Switzerland to reach Weil am Rhein. Thus, the transition can be made either in Weil or in Muttenz or even in Basel Bad and for passenger trains and in exceptional cases for freight trains in Basel SBB.

This requires the Swiss Infrastructure Manager to have Indusi in addition to EuroZUB/ETCS L1LS into Muttenz and it requires the German Infrastructure Manager (IM) to have EuroZUB/ETCS L1LS in addition to Indusi into Weil am Rhein.

Now, the German IM is always DB Netz. But, because the infrastrucutre to Basel Bad until the Rhine bridge is owned by the German State, IM for this Swiss infrastructure is also DB Netz. They have to obey Swiss laws but generally build to German standards.

At 2:40 you can see tow Eurobalises for EuroZUB/ETCS L1LS followed by Indusi on the right hand side, again at 2:44/2:45, at 3:44/3:50 and at 4:08/4:12.
