Now enforced by a 25mph timing section on the first automatic signal inside the tunnel, something that superteacher and I remember before installation! The timing section has always been there for A655. The speed limit used to be 35mph into the tunnel mouth, but was changed to 25 in the mid '90s due to the large number of SPaDs at A655. From Barons Court we'd go into full parallel down the hill into the tunnel mouth. Once inside the tunnel, slow the train to 35 then look for the reflection of A655 on the left hand running rail. If it was red then apply the brakes, if it was green then back into full parallel to Earl's Court. A SPaD is a SPaD and is a safety issue. As has already been said in this thread, it's not the actual SPaD that's the problem, it's what the T/Op does afterwards that's the issue. |

(My bold) If a reflection is what was relied upon then it doesn't surprise me this signal was often passed at danger! |

Looking for the refelction to change just allows the T/Op to go into full parallel earlier and go faster. It's all about knowing the road. |
