They put a loader at the back that hangs on to 2 pieces of rail then the train moves forward on existing track for rerailing . for new track the train backs up to where the track finishes and loaders drag the rail into position . in Australia 350mtrs is the maximum length of pre welded rail as it will derail the train on tight curves . Each length of rail has bolt holes for fish plates so they can be bolted together temporally until they are thermit welded permanently . You can have as longer section of rail as you like 10 100 kms long as its only the last 6 inches that expand the rest goes into its mass .
It should be as new passenger rolling stock is quite capable of 180 kms the thing is eventually it hits old per way and that's what slows it up . As you need more super elevation around curves (some places call this cant ). Bigger distances are needed for crossings and turn outs (leads ) Etc the faster the train is travelling . Reason !, a train travelling at 100 kms for example will pass a signal quicker than a train traveling at 20 kms per hour . So the trigger for the signal has to be further away , So it gets complicated if you have slow rains and high speed trains on the same track .
How unload long rail from train in to sleeper

This one Copasa arabia cemp work base 3
Can Saudi Arabia build a rail thru the red sea ?
The next project is to connect Jeddah with Riyadh by rail which is the most difficult project...
ALL FUTURE RAIL SHOULD BE HIGH SPEED

ALL FUTURE RAIL TRACK SHOULD BE HIGH SPEED
Great, so lmathia thought they can ride on it. This world is full twisting & manipulative creeps
ALL FUTURE RAIL SHOULD BE HIGH SPEED
