OO Gauge 144, Hornby Coronation Derailing Update

[@barryjgalbraith2635]

Glad to see that you are making progress. Your perseverance seems to be paying off. To paraphrase an American fighter pilot I know who told me that 90% of flying can be utter boredom the other 10% is sheer terror!! With model railways it can be 90% joy but 10% utter frustration!

Lovel video Ken you put together liked thanks DD.

I was going to buy a used coronation from TMC , the model centre, and raised this concern with them about being prone to derailing. They keep telling me that 'they are designed for 2nd radius and won't be a problem re derailing'. And if I have problems I won't be able to return it as its not faulty. So no sale...... honestly, if a loco doesn't run on a track where all your other locos run fine then there is a design issue. I'm never going to use that store.

Hi Ken. Have you done extensive research to determine why running through points in a facing direction is so bad? Is it a defect in the point manufacture? Is it a defect in the installation (sorry!)? Or something else?

[@kleedhamhobby]

I can't say that I've done research as to why, but I think if you just look at the points you can sort of see why. When a train goes through a trailing point there really isn't much to cause the wheels to derail - it can still happen, if the wheels are too tightly gauged to fit over the guide rails, or if the flanges are too big to fit through the frog; but those things excepted, there's no real reason a trailing point will cause a derailment. On the other hand, when passing through a facing point, there are various rails and guides turning off, and if something isn't quite right, it can catch on those and be pulled right away from the straight rails. Even when there are gauge or flange problems, there's some chance that a wheel knocked off the rail may get back on when passing in the trailing direction; but, as I say, if everything doesn't stay firmly on in the facing direction, there's a good chance of things being knocked sideways. That's my best understanding, anyway. It certainly seems to be the case... so if you have something that can't get through facing points without derailing, it's always worth giving it a try with only trailing points, if your layout allows that.

I can only run mine on radius 4.

derailing problems are caused by unlevel uneven track laying you need to do something about your voice

[@Danthehorse]

Not always, it can be due to a myriad of issues, often with the compromises in model loco design and bogeys. I've had derailing caused by track connectors being off by a miniscule amount, not even visible.
