A 3'6 narrow gauge single track tunnel based on those used in the United States in the late 1800's to early 1900's.
This 'Large' version is intended to compliment the djb_Old_Tunnel_1T_36NG tunnel. This one has a larger portal structure so that it can be placed at angles other than due North, South, East, or West without leaving a hole in the terrain.
This tunnel is based on the standard gauge version (KUID 55396:38010) which it requires in order to function.
This tunnel requires Mike Banfield's (aka Mike10) 'MB_NG_Track_3-6_new' track (KUID 35412:38106) which can be obtained from the Auran Download Station or from Mike's web site: http://www.mbanfield.pwp.blueyonder.co.uk/trainz/index.html
