safety margin Explanation: Am impresia ca e vorba de o distanta de siguranta permisa fata de semnalele respective. Pura speculatie, fireste. A.2.1.2.3. Semnalele de ieşire şi de parcurs pot fi retrase faţă de marca de siguranţă, cu o distanţă de cel puţin 100 m pentru directă şi 50 m pentru linia abătută, distanţe denumite drumuri de alunecare. Regulament din 04/08/2006 Publicat in Monitorul Oficial, Partea I nr. 814bis din 03/10/2006 de semnalizare nr. 004 By this point, it will no longer be possible to prevent a SPAD, but an effective train protection system will be able to prevent the train from overrunning the safety margin beyond the signal. A measure of the effectiveness of a train protection system is thus its ability to reduce the number of SPADs which exceed the signal safety margin. Railtrack maintains a database in which SPADs are classified according to their nature and severity.

overlap Explanation: "The train stopped just inside Block 3 is protected by Signal A125, but only if the second train stops at the signal correctly. Should it run past the signal, it will get "tripped" by the trainstop of A125. However, there is insufficient room for the train to stop before it collides with the first train. The safe braking distance is too short. To overcome this situation, each signal is moved back a safe braking distance from the entrance to the block. This distance is called the overlap ... The overlap now provides a safe braking distance for any train which overruns a signal so that there is no risk of it colliding with a stopped train in front."
