Jointed track & restrictions

[emoaconr]

Just an enquiry!
How much does the usage of jointed track affect the speed, and type of trains that can ride upon it?

I know my local line, Borderlands line, is primarily still jointed, which took 142's off it a good few years back, because of their rickety-racketyness which was intensified by having jointed track. Does it also reduce the speed limit, however?

The track between Shrewsbury and Chester is jointed in quite a few spots and the speed is 70 for sprinters/MU and 60 for eveything else

I dont think it generally effects the speed limits on the lines where it is still used(because the linepeeds are generally low enough), however I think if it were in use on the WCML or ECML for example then it probably would make a considerable difference to linespeeds, you wouldn't want to be doing 100-125 on jointed track!

When Mallard set the world record for speed, wouldn't it have been on jointed track?

Likewise she took regular runs at 100mph+ wouldn't it also have been generally on jointed track?

Jointed is okay for up to 100mph I understand.

Her wheels must have been knackered!

If the joints are permanent i.e fishplated then I'm not aware if there is an upper restriction or not, although the fact that it is still jointed would indicate its not a major route and probably wouldn't have a high linespeed anyway.

A temporary joint (i.e clamped with fasetta clamps) is limited to 50mph (20mph if the gap opens more than 10mm), and must be removed from CWR within 21days.

90mph tops on 60ft jointed rail, as far as I am aware.
