In the 1960s, early German electric traction was starting to take a proper shape, developments were being made, and for the Deutsche Bundesbahn, a mixed-traffic design was due for production. The new locomotive would be able to take advantage of the expanding electrified network, bringing newfound power and speed to passenger and freight services throughout Germany and even into neighbouring countries. Initially a small batch of pre-series locomotives, classified as the BR 181, were built in 1966 and put to the test; engineers analysed them and their unique dynamic braking abilities. 4 of these locomotives were built, two were known as the BR 181.0 and the others were the BR 181.1s. these will run 47 freight services from ashaffenburg to gemunden and will also do freight to the dockyards
Do you mean the Aschaffenburg docks? Those aren't electrified, the 181 couldn't operate there. I also made a suggestion that could have the 181 on it, and actually utilises it's multisystem abilities: Luxembourg - Trier.
These don't fit on MSB at all. The BR 181 was a multi-system locomotive for international traffic between Germany, Luxemburg and France. They were most common in the South-West of Germany. I can neither recall nor find any data that proves that the BR 181 was ever used on the Spessartrampe or in this region. The BR 151 would be a much better suggestion. It was used on MSB (mostly as a bank engine) and could be layered on other German routes for heavy freight trains.
