I'm not aware of such a practice anywhere in the world, except the UK.
I'm quite sure it never existed in Switzerland, for several reasons:
The practice is the more efficient the faster a train can go. For a long
time Switzerland didn't have speeds in the range that you fond in the
UK. Early electric locomotives reached 100 km/h or a maximum of 110.
Only the Re 4/4 I (1945) brought that up to 125 and the Re 4/4 II (1964)
Electric locomotives accelerate faster than steam engines. Loss of time
to reach 110 km/h again with an electric locomotive is not that much as
a to reach again 160 with a steam engine.
The practice only helps in one direction and only as destination. E.g. a
coach dropped in Aarau from a Zürich - Olten train only helps passengers
Zürich - Aarau. It doesn't help for
- Aarau - Olten
- Aarau - Zürich
- Olten - Aarau (however, this could be dropped from Olten - Zürich).
