Stressing is a technique developed in the 1960s to avert rail track problems that can occur following installation of Continuous welded rail (CWR).
When installing new rail, or before the onset of hot weather, the rail is pulled or stretched by hydraulic tensors or heated along its entire length to an equivalent length to that which the rail would be at 27 °C (in the UK), which is known as the Stress Free temperature.
Unconstrained large sections of steel will shrink as the temperature drops, and expand as it increases. Since the ends of CWR are fixed, the rail will experience tensile stress in extreme cold and can fracture if it grows too great. In extreme heat it will experience compressive stress, and if that force grows too strong the tracks may buckle.
Many conditions affect the stability of track when under thermal forces. The temperature in the rail plays a great part but stability is also affected by ballast, sleepers (type and quantity), ballast shoulders, areas of shadow or tunnels and bridges, track consolidation and to a lesser degree vertical curvature of the tracks.

This Is Stressing Me Out
There she is, never letting go
In a monastery inside Soho
There's a paintbrush
In a painted hand
And she's caring for me
Cause she cares for her man
Whoa
She's a poor crusader
On a distant ship
She's a miner for time
On a broken tip
She's a fiery deity
She's a pauper in this society
It can't phase her
It can't put her down
It can't phase her
It can't put her down
She's looking out the window
Catching the full moonbeams
She's looking out the window
Checking out what she can see, yeah
Cause there she is, never letting go
In a monastery inside Soho
There's a paintbrush
In a painted hand
And she's caring for me
Cause she cares for her man
