A recent 10 day visit to Europe, covering several countries (Austria, Czechia, Germany, Hungary and Slovakia) produced plenty of required locos and power cars.
List organised by the country they're registered in (as per the EVN) rather than country of operator, owner of anything else, as the increasing amount of leasing means it's more and more complicated (e.g. the list below includes locos registered in Germany, owned by an Austrian company, leased to a Slovenian operator, which were had on Austrian track).
