NRM Article - Tunnels

[mumbles]

nice one danny
i'll guess that little pic will have to do for an update on your layout
seriously though, good article, makes me think there's a carpet shop down the road from me that always has the inner cardboard tubes outside ready for the bin, like giant toilet roll tubes!
might have to investigate [although they are probably too thick]

Is the midde picture Blea Moor on the Settle Carlisle?

Just me, or is that a OO gauge tunnel with N gauge track and Class 158?

[m8internet]

That isn't an N gauge tunnel
I've got one and the bricks are WAY TOO LARGE!
The clearance at the top of a 158 is about 30mm at the most
From that photo you could fit another 158 on top!

Great article.

How come you've got 00 items? I thought you just did 'n' gauge!

[dr5euss]

Aww that last pic shows how cute N is

Good stuff Danny!

As for the 125, if it ever needs a new home in the future, gimme a shout...though make sure its later than sooner as I'm utterly brassic for now, lol!

Tunnel mouth looks excellent and your explaination is nice and clear and idiot proof (hell, if I can understand it... )

Good work matey

Here's another way to build tunnel mouths:

Looks great! How long does scribing the stonework take?

A couple of evenings - it's one of those things that once you get into it and discover a technique, you can do it fairly quickly.
A third evening is necessary to do the tidying up work (filling in corners, re-scribing thereof etc).
The scribing is done with a mini counter-sink in a dremel with the 1m flexible extension shaft. Provided the plaster is not too hard (care needs to be taken in the mix and I find mixing wallpaper paste in helps), the scribing is generally quite quick, however, it is a very dusty process, best done in a well ventilated area and definately using a face mask to prevent inhalation.

My first attempt at this method of construction was:

This took about a month from start to finish - too long!

Nice article. Like the interior of the tunnel mouth too.

Nice one Danny.
The toilet roll tube and brick paper's a great idea. Presumably a larger cardboard tube would do for 00. My tunnels look awful as they're just the entrances and you can see the walls of the room through them. I might be able to fit one of these tubes in and glue it in position.

George - your one liners are great. They bring a bit of humour to the read! I hope you post some if I ever do an article.

No offence but isnt that tunnel portal a little too large?

Not at all - it's based on the western end of Dainton. If you have a look at photos of Dainton, you'll see that the top of the arch is almost twice the height of a train.
Remember that Brunel built very large tunnel mouths on this style of tunnel. They were also built for broad gauge.

Also, to get the size correct, I actually used a photo and digitially adjusted it while maintaining aspect ratio. It is very slightly wider/height than it should be (only a few mm) by virtue of the fact that we have the wrong gauge of track and we place our model track at wider separations due to our curve radii (which is 5 foot in the picture).
This makes my model very slightly over scale. If I didn't maintain the aspect ratio, the overall proportions would definately be wrong and it would look totally wrong.
