Pendolino derailing

[ian_foley]

Hi I was fortunate to receive a new hornby pendolino train set for Christmas but unfortunately after running it on my third radius track it has started to derail on the bends.It is not being run at a very high speed at all and none of my other trains do it at all, hoping to find an answer out there please thanks.

Try running it VERY slowly, and see if you can spot the exact cause. It might be a mis-aligned rail joint, or maybe something is catching as it goes into the turn.

Does it derail in the same place every time, or a different one?

And welcome to the forum. All you have to do is ask and you'll get 20,000 different answers!  :-)

Hi 2e0dtoeric

thanks for reply,at the moment it seems to only do it when the power car is connected to the rest of the train and only in one dreaction that is with power car in front.I will be running it later today with different combinations to see what happens then.

Looking from the side see if the train car is lifting the power car bogie when you connect them.

 

I've see this often on steamers where the tender lifts the front bogie.

 

Also check the wheel back to back dimensions as this is a typical derail cause..

Ian - please do NOT use the blue QUOTE button to reply to a post. Scroll down the page to the blank white box underneath, type in there, and use the GREEN reply button!

That way the original post doesn't keep getting repeated all down the pages, and your response words don't get lost!

Oops yes sorry about that I realised after I had sent it,update so far cleaning all of the tracks I did reverse train and it hasn't done it so far but will take notice of both contributions and will act accordingly.

Gday Ian. I have the DCC fitted Pendolino too and it has been a problem child from day 1. Check that the drive bogie can pivot freely. I found a tiny screw jammed down next to the motor, stuck to a magnet which prevented the bogie from turning. As with you, it only derailed when carriages were attached. The tilt mechanism also played a part so check the front bogie too. If it is stiff, the rear won't rotate as the body is still upright.

Another problem is the dummy car decoder. Couldn't read it at all and even though I could change the loco address for the power car,when I did, the lights wouldn't work in the dummy car. The only solution was to leave the power car at address 3. And now there is a pickup wire broken internally somewhere so when the front bogie turns  slightly, the train stops dead.

You may find that - to get the dummy car decoder to work - you have to swap it with the one in the power car. You often find that the decoder won't re-address unless there is a motor connected to it!

So re-set the power car to whatever code, then swap decoders from power to dummy, and v/v, then do it again, re-setting the power car.

You may be able to put both the power car and dummy on the programming track, facing different directions, of course, and re-set both at once, or you may find - as above!
