Timber rails were not used with motive power much at all.
They were primarily used for horse drawn logged or sawn timber.
In cases where it was used, steel rails would be used on curves,
or the timber may have flat metal sheet nailed on to them.
Where locos were used, the weight of the loco,
would quickly cause the timber to break down.
In addition straight pieces of timber were used on curves,
so the gauge on curves would vary with distance.
Hence the wide tread.
Another option is pole roads and double flange wheels.
