Layout help

[Retrojim]

Im trying to plan a new layout using Hornby track. Im hoping to create four oval lines but my space is impeded by pipes which I need to work round. Can soneone please tell me if I am on the right lines (picture below) with each radius and what do I need to complete the forth line./media/tinymce_upload/727a24dfe684f70e05273498e4ba46a5.jpg

You could use flexitrack, in fact all of those curves could be done with flexy.

I agree with rog, flexi track would be good!

Me too.

I recently used a load of flexy for the first time and was pleasantly surprsed with the results. Not as difficult to install as I imagined and it comes in big long sections. Bought mine second hand but am I right in thinking that when new it is cheaper than set track?

[walkingthedog]

Yes cheaper. The longest set track straight is about 26 inches and a length of flexi about 36 inches. Both are the same price. Curves work out even dearer. 

[Jeff Mennell]

I wonder why folk don't just buy flexi (with track templates say), when constructing larger layouts? Less joins etc Would be a lot cheaper....almost seems to good to be true?

[walkingthedog]

I agree but on my layout if I need a 4th rad curves I'll buy Peco set track. Easier to lay in areas where you need to stretch across the layout.

Apart from the points - Peco Express - all my track is either flexi or semi-flexi, dependng on what was to hand at the time! Flexi is easier on full curves, but semi-flexi is good for little wriggles around scenery - but someone is bound to say the reverse is true!  :-)

You need to do the 'pencil taped to a long carriage' check at the smallest radius inner curves to check for adequate clearance around that obstruction first then space out the other lines to suit from that datum line.
