You also have to understand when the DB and DR started to build locos under the E and V codes they kept gaps for each others locos.
eg DB E40, DR E41.
There was a DB E41, but no DR E41, but there was a DR E42
Not sure if these gaps were deliberate, and its not 100% true, especially for Diesel (V) locos as there were V60s and V100s on both DB and DR (hence the confusion about the DB V100 in your picture) talking of which...
...and referring back to earlier posts - it is most definitely a DB V100 in your picture, not a DB V90 nor any DR version. IMHO It's easy to tell the difference between DB and DR V100s. The latter are much more angular with a flat cab roof and a distinct pitched top to the two 'noses'
Incidentally the DB V100 were built from 1958, the V90s from 1964 (essentially following on from the V100s) and the DR V100s from circa 1966
Your picture is 212 325-5 now owned by EfW-Verkehrsgesellschaft mbH, Frechen (a suburb of Köln). As its a 212 it is actually a V100.2 originally. Built by MaK wks nmbr 1000372/1966
DB (and DR) V100s were not shunting locos but mixed traffic. V100s hauled secondary passenger and branch passenger trains and lighter freights. V90s were (are) mainly heavy shunters but also trip freight locos.
The green E40 is a DB museum loco from nearby Koblenz:

And I agree I think the second lok is 140 423 which is also based at the Koblenz museum and is in Turkis/beige
