Why Wooden Sleepers are better. Was [NSW] CityRail Delays Friday

[The Railway Rasputin II <bob@fastlink.com.au>]

Wooden sleepers don't weigh as much and therefore are less lightly to
sink and deform the rail. (smooth ride) 
They don't crack.
They don't echo flat wheels as much as concrete.
Most importantly, if the train derails the wooden sleepers break/give
way so that the wheels don't bounce up and down which can tip the
carriage. 

The only real advantage concrete has over wood, is that wood has to be
replaced more than concrete.
