Jacobite Stalls at Beasdale

- "The Jacobite" is touted as "The world's greatest train journey" and we joined the fully booked train in the company of tourists from home and abroad.
It was a perfect summer's day at the end of May 2012 and 62005 had a full head of steam on dry rails.
So, what went wrong on the 1 in 48 incline and reverse curves on the approach to Beasdale?
The word was that, following a trackside fire on an earlier train, the crew were trying to limit the quantIty of red hot cinders ejected onto the parched surrounding moorland.
Whatever the reason, we stalled just short of the summit.

It was a great day out for steam traction on this magical line!
Very good footage!
Judging by the sound of brakes, I wonder whether the vacuum failed?
went on that few weeks ago.wonderful trip
Certainly a reminder that Beasdale bank, 1 in 48, is not to be trifled with! The Mallaig line is very scenic but also a real test for any locomotive. But there are squeals on the first climb that are not there on the second at similar or greater speeds, therefore not just wheel flanges. So I would agree with those who reckoned that the brakes partly leaked on the first time, especially as the engine was blowing off as it stalled. The second time as well as rebuilding steam pressure the driver may well have ensured he was pulling the best possible vacuum before restarting, and the engine slogged steadily up the steepest part.
That sound must surely be brakes binding? Not the squeal usually associated with flanges on tight curves
Fascinating - many thanks for the video response. They got there in the end!
Stalls are caused by the steam engine losing enough boiler pressure to climb the gradient, as the engine starts to work harder and harder, more steam is being used and the rate it's being generated starts to drop, causing the boiler to lose pressure. As the boiler loses pressure, the brakes start to apply causing the engine to go even slower and thus' making it stall.
Went on it 2018 emotional.
That sounds as if the pressure was so low the brakes came on.
As I was recording the video I thought "they have left the brakes on" but later I was told it was the sound of the wheel flanges on the curve with the rising gradient. This is plausible as there is a similar sound on the second, successful, attempt at the apex of the curve.
Sounds to me like low steam pressure causing brakes to apply and needing to stop for a blow up.
Not the first Jacobite to fail since April 1746. Perhaps the train should be renamed The Hanoverian and be pulled by the Duchess of Sutherland?
