Physics teacher said expansion gaps in railways are a must to prevents rails from buckling during hot weather. Good! The trouble is gaps cause discomfort and noise as train wheels go over the gaps. Seems the gaps were not necessary after all,British railway and host of other Railway network have continuous welded railways which offer smooth less noisy ride. How come continuous welded rails don't buckle in hot weather?
In my views;
1. Gaps are not necessary in cold weather countries
2. In Hot weather countries like tanzania, Gaps are important if the pieces of the railway are merged, But if the Railway is continous and no junctions, hence gaps are not suspected.
3. If you join them using special thermal material then it will be OK.
TAZARA ni continuous welded rail(cape gauge) haipo nchi za baridi. Explanation yako haitoshelezi.
Revisit the meaning of 'Cape gauge'
TAZARA ni continuous welded rail(cape gauge) haipo nchi za baridi. Explanation yako haitoshelezi.
Simply pointing the fact that Tazara is 1067 width between rails moreover the rail was upgraded to continuous welded rail early 2000.
The fact you kept "continuos welded(cape gauge)" in one place as if cape cage is substitute to continuous gauge was wrong, and that was my correction. BTW umesahau kuweka units "1067 width" ndo nini?
Cmon we are social media space no rigour required. About units make an intelligent guess.

I am not a mechanical engineer, but can add from my physics knowledge. Suppose the coefficient of linear expansion of some material is quite quite negligible, can this be the reason?
