Yes, me too.
It is obvious, there is some advantage to use the same hand as your
neighbours.
On the other hand… it reminds me on a curious decision to do exactly
the opposite. When trains started to be build in Spain, we intentionally
used a different track gauge than France (1,668 mm instead of 1,435 mm),
with the explicit purpose of hindering invasions.
So our trains used “broad gauge”, and Portugal had to follow suit. I
thought we used the same as Russia, but the wikipedia says not.
Now, the new high speed trains are built to the same gauge as France and
Germany, I understand. Anyway, they need entirely new tracks and layout…

We also have some trains (starting with the Talgo) that automatically
change their wheel positions at a point near the frontier pass into
France. Previously, passengers had to board a different train just there.

The thing about escorting is new to me. But crossing other knights on
the sword hand, I heard it many times, told by British folk I met (“We
on the wrong side? No, /you/ are on the wrong side!” :-)) )
