Question:
Can German units in the Ruhr cities draw supply from the cities themselves or must the the cities of the Ruhr be connected by rail to another najor city in Germany?
Answer:
Per rule 3E2 a combination of adjacent full and/or partial city hexes is considered a conurbation and thereforeone city for game purposes. So you must be able to trace a rail connection from the Ruhr to another major city in Germany for the Ruhr to be a source of supply. Note that the supply rules specify major cities and not major city hexes.
