O scale autocoach radius?

Recommended Posts

Can anyone conform of the Dapol autocoach will go round 2nd radius curves / set track points? Thinking of getting one with the 14xx

It probably will...on its own. But you'll almost certainly experience buffer lock issues when coupled to a loco I suspect.

What radius is second?  I got one going round a 4'6" rad curve pulled by a Pannier.

it says that it will on the box. Have a look at the picture on this eBay sale to see. https://www.ebay.co.uk/itm/Dapol-7P-004-010-GWR-diag-N-Auto-coach-39-GWR-twin-cities-brown-cream/283645182443?hash=item420a9201eb:g:HGQAAOSwIRhdpyd7

 

I have no link to the seller, it was the first decent image that I found.

Two pictures showing the best and worse - depending on how the train enters the curve. The slight play on the wheels determines wether you get buffer lock on peco curves.

An auto trailer by definition spends about half it's running time being propelled, so this is a valid point.  Hauled by a 57xx Pannier, or any other non-auto fitted loco, it should perform as any other coach would, but is still more prone to buffer lock as the buffer shanks are very long to account for the extreme bow-end design of the coach.  If you need to propel it as in an auto working, or shunt it on tight curvature, you can easily run into trouble and need to establish a minimum radius that can be practically used.  If your radii are less than this, the only solution is to couple the loco to the trailer with a fixed bar type of coupling, which will result in the trailer being too far from the loco on straight track but will overcome the buffer locking issue.  This coupling will need vertical play if you have gradients on your layout.
