RMweb Premium St Enodoc Posted June 22, 2021 Author RMweb Premium Share Posted June 22, 2021 11 hours ago, St Enodoc said: I was working from home today, so at lunchtime I popped out to the railway room and did an experiment. I marshalled 15 china-clay wagons and a brake van and tried to propel them up the curved gradient from St Enodoc towards Wheal Veronica. 1664 (Nu-Cast) had no trouble but 7446 (Bachmann) did. It managed to get the whole train on to the incline but no further. Even a reduced load of 12 wagons plus the brake van was too much so clearly Something Must Be Done. 7446 weighed just over 200g. There isn't much room for extra weight but tonight I've squeezed some lead into the front of the boiler between the lower casting and the decoder, which has brought the weight up to about 225g. If anyone knows how to get into the bunker there might be some scope there too - there are three screws underneath but removing them doesn't seem to make any difference. I should have time to try again tomorrow. Phew! Between breakfast and starting work, I went out to the railway room for half-an-hour and found that, with the extra weight, 7446 will push 12+BV without slipping (13+BV with some slipping but no more) up the incline as far as the end of the track so far. On the basis of that I'll leave the bunker as it is (it already has real coal glued on top of the plastic stuff) and press on with tracklaying at the weekend. 17 Link to post Share on other sites More sharing options...

Baz Yes, as we and others know, it was done to get the Edinburgh/Glasgow push-pull set up the bank from Dewsbury Midland to Leeds Victoria (if you don't know, don't ask). However, in this case the simple (and elegant) solution of a bit more weight has worked, so I'll stop while I'm ahead. 7 2 Link to post Share on other sites More sharing options...

Paul. Serious head on. It was because the DBSOs only had fixed increments on the traction power control, as the regulating air pressure was determined by combinations of EP valves on the loco selected via the TDM system. The 47/7s, on the other hand, had infinitely-variable regulating air pressure through the power controller. Consequently, the decision was taken to run with the loco at the Edinburgh end to provide finer control and minimise wheelslip up Cowlairs bank. 6 2 Link to post Share on other sites More sharing options...

P.C.M Posted June 23, 2021 Share Posted June 23, 2021 Hi John, Just having a bit of a catch up. You are certainly cracking on the layout is really coming together and looking good too.

I knew that a push pull set that went from Edinburgh to Aberdeen couldn’t be put on a Glasgow diagram as the engine would be on the buffers when it got there. Now I know why.

RMweb Premium Popular Post St Enodoc Posted June 25, 2021 Author RMweb Premium Popular Post Share Posted June 25, 2021 A late birthday card arrived yesterday from an old University mate (one of the four of us who have birthdays in June and so shared a monster 21st party in 1977). It read: "You may be 65 but remember... . . . . . . . . . . ...it's only 18 in Celsius!". I reckon that's a good way to look at life. 4 4 2 10 1 Link to post Share on other sites More sharing options...

RMweb Premium St Enodoc Posted June 25, 2021 Author RMweb Premium Share Posted June 25, 2021 (edited) I laid a bit more track today, namely the last couple of feet of the Wheal Veronica branch and the point. The point is buried under the weights at the moment. Tomorrow I should be able to finish laying the two sidings.
