NO! Because when something fails on the single section whether it be a train or infrastructure the knock on effect is catastrophic!!!
If something fails anywhere it will always be a problem, that is not grounds to double a length of single track as the risk assessment will be low as not many failures happen on the short section of track and to be honest recovery of a failed train on a single track is an easier process on double as you can easily assist from either direction, the problems occur mainly when the signalling fails as you need a pilotman to pass over the single line, if this was the main problem resignalling would be a lot cheaper than redoubling.

Fully agree, ATWs biggest nightmare in North Wales is a failure on the single track between Wrexham & Saltney,it is classed as North Wales main pinch point.
In 6 years working over the single line I can only remember one unit failure

You couldn't run a train any faster along that section. Capacity is the issue! And I agree with making an IB section between Gobowen and Wrexham! Linespeeds can only be increased when they rid of ALL the jointed track sections. Especially BR1 and Lockspike type baseplates, of which there is plenty between salop and chester!

Just reading that again Planner but don't you mean between wrexham and gobowen? There is already an IB section between Salop and Gobowen approx half way at Stanwardine. There is 4 colour light signals in total in this area. 2 for each line, a distant followed by a controlled signal that are both operated from Crewe Jnc. CJ200 controls the UP and CJ201 the down, obviously once a train is passed either signal then another is sent straight in!
They are in fact controlled signals with axle counters however this is irrelevant. To get better capacity between Chester and Gobowen you will need at least 4 signal sections added. one between Chirk & Ruabon, one between Ruabon and Wrexham, One between Wrexham and Rossett and one between Rossett and Balderton, this will give you more capacity however I have not seen any documentation on planning these extra signal sections, once these are in place you may need one extra between Goboen and Baschurch to balance out the extra capacity and also another between Baschurch and Shrewsbury only this way will the whole line be balanced.
For example, a train leaves Shrewsbury for Gobowen, there is a 12 minute waiting time for the proceeding train to clear Baschurch, then there is another 12 minute pathing time from Baschurch to Gobowen, if you maintain linespeed even at 60 for LHCS when you approach Baschurch signal CJ201R will be at caution. The on arraival at Gobowen you have another wait of about 12 minutes for the train to clear Croess Newydd. The on arriving at Wrexham you have another 12 minutes for the train to clear the single line.
You will not obvioulsy wait 12 minutes as you have the travelling time to and from the signalling point but all this line needs is resiganalling to increase the capacity and doubling the line from Wrexham to Saltney

I am told there was chronic overcrowding on Sunday on the trains from Rhyl after the airshow, the local paper reports 100,000 lined Rhyl Prom for the event,I caught some of it at Talacre as the red arrows & wing walkers passed over.
Talacre light house is famous for Dulux dogs adverts,never saw one ,plenty of scousers though
Well that is abd planning on the part of ATW then as extra services should be provided when there are events like this, I remember Cosford airshow when there was just a basic sunday service provided, this is poor on the part of ATW as many folks are left behind missing the show.
