I was on a WHL train today and, when leaving Crianlarich, it got me thinking. What is the procedure for signalling trains into Crianlarich from the north?
For example:
If (just in theory) a service was running on the Oban branch and the Fort William branch, one of these services was late running and the units were scheduled to couple at Crianlarich:
1) If both left their respective Tyndrum stations at the same time, would both of the trains need to stop outside Crianlarich (ie does the radio token for BOTH services only run as far as the junction immediately before Crianlarich, or does the radio token for either the Oban branch or the FW branch allow running directly into the platform at Crianlarich?)
2) If this is not the case, and the token is for the full section for Tyndrum (Upper or Lower) to Crianlarich, does this mean that the service which left first would need to arrive at Crianlarich before the second service was permitted to leave the station at Tyndrum (this could surely add up delay minutes?)
3) I was on the Oban branch on the return today, and there was no stop outside Crianlarich. I’m assuming that this means the Oban token runs all the way from Tyndrum Lower into the platform and the FW token from Tyndrum runs out before the Junction and a separate token/permission is needed for the junction - the platform in Crianlarich?
