A day in the life of a jointed track

ΔG = αLΔT°. Free expansion

For a free thermal expansion jointed track the rails expand and contract freely and the track components do not provide any resistance to oppose this rail length variation. 1,180 more words

When a 20 m rail is 20 m long?

Perhaps I’m splitting hairs here, but it is a fair question to ask:

When a 20 m rail is 20 m long?

Jointed track response to rail temperature variations

The thermal behaviour of the jointed track can be analysed throughout a full annual temperature variation and used to define the joint expansion gap variations. The joint gap varies between the maximum value and zero and this is related to the way the rails are allowed by the track resistance forces to contract and expand in the joint. 1,922 more words

Dreaming of picnics and outdoor meals

We had a beautiful sunny blue-skyed day today after Storm Doris passed. My washing dried on the line and it was the sort of nice weather I wished I had more washing to do, but I am all up to date. 330 more words
