After a few load tests on my railway in recent days, I'm starting to wonder the weather the 'Caradoc' is suited for my line.
After steaming up (which takes around 10 mins), she runs around the railway perfect light engine, but when I tested her on rolling stock she really struggles. I set her off with 4 small LGB wagons (a very light train). She managed 2 laps (requiring full reg in the corners), after that she started running out of puff and got stuck on a bend with a very, very slight climb. I lowered the number of wagons to two, again she stopped after one lap. I left her to build up steam for a minute or so, then same thing. I then took all the wagons off and she could hardly managed without a load. Shortly after she ran out of gas, think the boiler was dry too. Was around 20 mins running time.
In a video I posted recently of one of her first runs, she ran fine Light Engine, though I had the burner up too high, as can be heard in the video.
I'm starting to think my line is way to sharp for her (all are 1st LGB curves), and she doesn't seem to have to time to build up pressure in-between bends. My Regner Conrad on the other hand has no trouble at all! Had her on a load 7, with 6 playmobil wagons and a Accucraft W&L Brake van and she make not hesitation in bends and on the slight climb.
Any idea on what I'm doing wrong? She really is a beautiful machine and love her to bits. Her jet did get blocked recently which I sorted, can't see that being an issue though?
Here's a link to a cab ride in the of the railway last year, showing the section of line I've been running on. The video from 3:57 should give you all a good idea of the curves. The corner at 5:01 is were she gets stuck. Hope it's of help...
