using the right track for new stock.

[davvydo]

when i got the gresley teaks for my birthday which was yesterday. no need for you lot to sing !!!

but i am at the moment in my layout re-building the whole of my track work to accommodate bachmann andhornby coaches which are getting better by the minute. BUT there is always a but aint there !

the coaches keep on derailing in the same spots, i have though of what it only can be is that the wheels are to near to each other and need pushing apart, did that, they ran smoothly, until i sat down. rattle rattle rattle i heared they were off again, the whole 5 coaches of them.

i was turnig to you lot for help until i saw a picture of a model loco by bachmann, (the 3F jinty)



then i noticed the track and how thick it is, could you tell me what make of track that is, i think it may be the track i need !!

That looks like code 100 track, but I don't the track is your problem, (well kind of).

Where exactly are they derailing? Is it on corners or straights as well. If it is on the corners, it may be that the radius is too tight for the bogies on the coaches.

[spartacus]

Much of the new rolling stock is designed to only go around second radius curves and larger (although most will go over 1st radius witha bit of encouragement.

Another problem could be if you're running stock with different couplings. Although this usually only makes a bit difference when propelling (pushing) the train, it can sometimes cause derailment problems on corners at other times. Then there are the new Hornby Pullmans, which are a law unto themselves, so I've heard and struggle to stay on the best of track.

[davvydo]

it is on the check rail of the points where the wheels love to come off. i have only ran the coaches with the bachmann K3, they have the same type of couplings.

i have actually worked it out !!

it is the bogeys and the couplings themselves. when the full rake is together and they go over a right hand or a left hand point and go over a checkrail they come off. i think it is the couplings and the bogeys combined. i think i might change the couplings to make them close coupled. that might make a difference.

[BR7MT]

Are they the standard shape of point that come with train sets? If so the coaches will not normally traverse these without derailing,

I suggest you get the express turn-outs which have a higher curve radius. You will however need to alter your track layout and they may not be suitable for use in a small space.

I bought 5 bachmann Mk1's at Donny erlyer this month and I fitted them with a close coupeling bar which came with them. I pushed them into a sideing and whan I came to move them with a loco the loco just sat there with it's wheels spinning. The sideing has two 1st radius curves on it and it was so tight that the coaches wouldnt move.
To remidy it I parked them in a different sideing which had 2nd radius curves.

I bought a Hornby BR livery Gresley at the same time and paired it with two old Bachmann Thompsons. I havent had any problems with the Greslesy just with the Thompsons but they have allways been bad to push around the layout especially over any points. (the Gresley and Thompson carrages have different coupelings but ran well together)

As BR7MT said it may possibly be the radius of the points. With only one Gresley (at the moment ) My experences have been with it paired to other coaches with different coupelings. My Mk1's had the same type of coupeling and preformed well.

[BR7MT]

The Bachmann Thompson coaches are pretty awful. I have two brake coaches and have had to leave them in the carriages works because they derail so much!

The problem with Bachmann Mk1s is that the bogie rubs against the chassis when on 1st radius curves, plus they weigh too much and most don't exactly freewheel. One thing tender drive is good for is power!

[BR7MT]

With the Thompson's I have the wheels hit the underside of the body. Had to file away a lot of plastic to get a half-decent performance out of them.

I havernt put my Mk1's on any 1st radus curves any more. (I dont like seeing a loco sitting in one position scratting )

The only problems I have with my Thompsons is pushing them though point work. Although if I can get the loco to go slow enough they stay on the track (Bachmann 08 time ).
