Someone has dropped a clanger, as the Water Bowser normally provided at Huntingdon wasn't booked. This info from a member of staff at Huntingdon. Also, although she was booked at Huntingdon for about 20 minutes, her stop there caused a following...

I would say that the unburnt fuel loss was more due the amount of fines that were generated by the screw feed system, which simply passed straight through the tubes and out of the exhaust without ever properly combusting. Take a look at the...

Well no, it rather suggests that you have reached the limits of gigantism in steam locos and need to think of diesels or electrics if you want to increase power! The only places which seemed to be able to make giant steam locos work was where...

What has to be remembered, when moaning about the diesel doing most of the work, that the cross section of passengers on the train means that there is practically no option to cancel the train when Network Rail impose Red restrictions to steam...

The diagrams show 37688 as being out but the list of locos doesn’t. There’s an error somewhere. Mind you, it’s not unusual with the daily running sheet, which is often a cut and paste job.

Into Tamworth 50 late. Nice sprint up to 75mph, few smuts come through window, so steam doing a little bit of work at least.

Nope green headboard is still on the front, 47 802 doing all the work from the rear. Andrew

Stephen Hughes liked Johnb's post in the thread RTC: End of Southern Steam - 9/07/26.
Best comment so far. When I walked round Nine Elms on 10th July 67 with some engines still showing pressure on the gauge there was no way would I have thought we would be where we are now. Well done to NR, RTC and MNLPS for making it happen in...

Sorry, I don’t understand that? Are you saying that fitting a mechanical stoker has neglible impact on efficiency? Because my understanding was that typically you’d burn about 25% more coal for the same output. Which rather screws your overall...

How do you propose to fire a 6,000hp steam loco? That’s well beyond the capability of a single fireman, so you fall back presumably on a mechanical stoker - which rather throws away the enhanced cylinder efficiency by creating worse boiler...

6000 ihp is power of 3 LNER V2 working flat out. The Chapelon compound 152 goods engine was planned to pull fitted freigth at max 105 km/h. 700 american built 141 R,ca 300 141P and 25 240 in France had stokers. Stokers lowering boiler effiency...
