Patent FR-2383814-A1 (FR)
Inventor: MICHLER MARTIN
IPC: B61L3/22
Filed: 1978-03-17
Abstract: In the automatic continuous control of trains, the locating of the vehicles relies on the boundaries of the route areas as locating reference points for the vehicle-side fine travel measurement device, marker points (M) within the route areas permitting fault correction of the fine travel measuring device. The latter permits up to four non-detected marker points to be bridged. Since the area boundary (BG) must at the same time be a marker point, a failure of the line-conductor slide lying directly in front of the area boundary in the direction of travel would be particularly critical. In order, even in this case, to keep the number of non-detected marker points which can be bridged smaller than four, the slides (L10, L11) adjacent to the area boundary (BG) can only have the length of half a marker point interval whilst the respective next slides (L9, L12) have a length of two marker point intervals. Only the third slides (L8, L13) on each side of the area boundary (BG) have a normal length of three marker point intervals.
