Question

How long welded rail panels are being transported in European railways?

Answer 1

The rail lenght in 1440 ft. They are place in the track and then are welded to the other rails.

Panels are 39 ft long and can be jointed or welded.

Answer 2

Question is worded a bit confusing, do you mean what is the length of welded rail panels?

Not sure, in the States I have never seen a welded rail panel, they are always one rail length and hauled on flatcars to put down for "instant track" after a deraliment or washout.
