What kinds of rail joints does IR use?

18-07-2019

Fishplated joints are the most basic joints seen, on lines where there is no track-circuiting, and no welded rail in use.

Usually there are two bolts securing the fishplate on either side. There are variations in the basic fishplate design to account for different weights of rails, and joints in special situations such as on sharp curves, at points, etc. For 60kg/m track, while the rail specification is very close to Revised British Standard, the fishplates (and fishbolts) are considerably stronger than the British

A characteristic feature of most passenger stock on IR today is the presence of welded bars on the windows.
