Hello

I find that most of the track combinations that I require cause clashes of sleepers between templates which cannot be simply resolved by rolling sleepers.

Clearly the resolution is to use the shove timbers functions, however I have not been able to find a source of information/ set of rules for setting out sleepers prototypically.

Can anyone point me in the right direction please? 

Thanks

Dave

Hi Dave,

We've been here before. :)

See: http://groups.yahoo.com/group/templot/message/8313

and subsequent discussion.

To get that message into the site search for reference, here it is again:

I can see that the 'shove timbers' function depends
upon you knowing where they should be shoved to!
Is there a standard reference document to work from/to?
If only! Timbering a complex formation is something of
a black art. When you think you know something about it,
along comes a photograph showing the exact opposite.

Some guiding principles:

Special switch and crossing chairs can fit the rails only
at pre-determined positions. They must have some timber
under them. This often means using more timbers, or wider
timbers, so that the chairs are firmly supported and the
chair screws are not too near to the edge of a timber.

Timbers should be as near as possible at right-angles to
the rails. This creates the strongest track, able to resist
gauge-spread. This is especially important on curved tracks.

Timbers must be able to be packed up level if necessary.
This means that the gang must be able to dig out under
them, insert jacks, and place fresh ballast. This is very
difficult to do if timbers are very close together side by
side or end to end.

Rail joints are the weakest parts of the track. Timbers on
each side of a rail joint should be as close together as
possible. This generally means joint timbers are spaced
at no more than 25" centres, so that a standard fishplate
just fits between the chairs.

There is more about timbering practice in these messages:

but we are still waiting for the definitive guide. Anyone?

Before even beginning the shoving, it's sometimes worth seeing if a different basic timbering style would help. More about that at:

A black art indeed. Clearly I needed to spend more time looking back in the forums.

Thank you for your reply
