STornado problem

I have an issue with my Tornado. On the straights it runs beautifully yet as soon as it comes to a bend (rads 2/3) it stops. All my other locos are fine including the identical Bon Accord. I've cleaned the wheels but it's not solved the issue.

With regard the bends. Is it a left bend or a right bend or both. Also, does the issue also happen if in reverse on the bends?

.

If for example it is only a left bend, but turning to the right is not an issue (or visa versa). Then I would suspect that the axles are moving sufficiently sideways to allow a wheel pickup to come away from a wheel (lack of pickup tension).

.

Note regarding left versus right. On an oval, with the loco going clockwise in a forward direction, the bends will always be to the right. Turning the loco round to face the other way and driving anti-clockwise in a forward direction, the oval bends will be to the left instead.

The problem seemed to be on left hand bends (anticlockwise), in both directions.

So following your advice I turned it around to go clockwise and after a couple of semi stalls it worked properly. I ran it in that direction for a few minutes, turned it around again and it now seems fine. 

Could it be getting ready for new pick-ups?

Either that, or a strip down to remove the pickup assembly, re-tension the pickup wipers and put back together again.

I have often had trouble with Hornby locos having insufficient tension, or no tension, on the pickups.

My latest acquisition, Hornby's Patriot Class 'Ranger' was particularly bad. Easy enough to fix, but you shouldn't have to.

Gorgeous loco, though.

@Spireblade........turn the loco upside down and see how well the three driving axles slide from side to side.......often these need lubricating to ensure free movement so bends can be traversed easily........needs a long needle with a tiny drop of oil to get down to the axle bearing........just a thought......HB

Do you know who I am?..........No, but I'm sure Matron does!

After running it in the other direction for 20 minutes at a high speed it now seems fine.
