Eggrbahn as Tootnkumin says is H0 scale on 9mm track.
Both locos are highly collectable in Europe as all models were taken over by the French firm Jouef in 1967 after the ending of the original company.
The Jouef versions are not supposed to be of the quality of the original Eggerbahn models hence the value, especially the electric loco with the pantograph.
Here is a link to an Eggerbahn site.

Here's a photo of my new mini layout under construction which has Eggerbahn/Jouef items and another 60's item, Eheim/Brawa Trolley busses.
