Abstract
An electrically driven rail or track bound vehicle which can be supplied with electrical power from an overhead wire. The vehicle includes a current collector carrying at least one bow trolley, with the current collector being adjustable to varying levels. A width of the bow trolley is automatically variable in such a manner that, with the current collector being adjusted to a low level, the bow trolley is narrow and with the current collector being adjusted to a high level, the bow trolley has a wide width. The width of the bow trolley is variable continuously with height variations of the current collector.
