Erlangen-Höchstadt goes back to the 1972 merger of the erstwhile Erlangen and Höchstadt counties (Landkreise). It is a pretty eclectic mix of suburban areas oriented towards Erlangen and more rural areas where agriculture was at least traditionally important. Part of the county is also famous for the Aischgründer Spiegelkarpfen which leads to many a village having more carps than humans.
S1 serves a few minor villages in the county on its way from Erlangen to Forchheim and the Gräfenberg-railway serves a few stops inside the county. Other than that, all railways were shut down in the 20th century, meaning you'll have to rely on buses
