There have been some postings about tunnels this month so I hope no-one will mind if I show some of the tunnels on my trainset of the Goon Valley Railway. All except one have been scratch built. This is the method I prefer as it is rare to find a kit or ready made item to fit your requirements exactly, and nothing beats the feeling of satisfaction on making it yourself.
There was some concern about the width of one of the kits . I suppose it is better to have a large bore than a much too narrow one as the driver of LMS Garrett quickly found out when he tried to enter Greenslade tunnel recently
This is a straight forward cardboard construction with Metcalfe embosed stone buiding card overlay.
The second picture shows just how narrow this is but in fact will accomodate the usual branch line traffic without problems . The other two track tunnel beyond the bridge is also cardboard with embosed stone overlay of unkown make but I think it is for O gauge.
Pic 3 shows the other end of Greenslade station . This tunnel mouth is a plastic kit (Wills or Ratio?) most of which was not used. The chalk cliffs are cast using alluminium kichen foil , crumpled , opened out ,filled with a rather runny plaster of Paris, and literally slopped onto the base ( expanded polystyrene).
Pic 4 is a very simple one on the Grand Union Canal . Same cardboard construction covered with brick paper by Prototype Models. This tunnel burrows under Ellington loco shed -still to be built.
Pic 5 is on the lower main line and this takes the double track beneath Min Tor. A similar one but single track takes the freight only line under Min Tor to the Ellington yard and shed and is just visible above the second Gresley coach.
Pic 6 shows the other end of this tunnel but has twin mouths .The sets of points will eventually take the lines into
the terminus station at Secombe.
pic 7. shows two similarly built tunnels the upper one with the tracks going nowhere will oneday hopefully carry the reversing loop from the lower mainline to the upper mainline.Both made of cardboard with cardboard overlays in relief all covered with Superquick grey slates paper No. 5. Here the bores had to be made through a concrete wall requiring the services of a contractor using concrete cutting equipment.
The bores themselves use large diameter plastic drain pipes and these can be seen just below where the track ends
Pic 8 shows the other end of this tunnel. It shows that the two sets of lines have reached the same level via inclines.
Built in the Art Deco style they are cardboard again with the stone work scribed with a blunt knife. I am loathed to dirty these but I suppose I will have to one day. The tunnels bore through Lion Hill, hence two lions guarding the entrances. I wanted crouching lions but these were all I could find ,both were fluorescent and the unpainted one reminds me every time I switch off the lights that I still have a lot of work to do in that area
Pic 9 This has appeared in my postings before - Cardboard covered with Metcalfe embosed stone papers . The other end is not shown but is similar. this tunnel takes the double mainline under the village of Bluebottle ( where the bluebells grow)
A further two tunnel mouths still have to be built taking the upper mainlines under the house !
