Good evening!  This auction features a BRIO WOODEN RAILWAY SET No. 3135-31404/35 with the original box, and includes a TUNNEL section No. 3362-31405/12, 8 1/2" long, with the original box... both date to the early 1980's, and are in extremely good condition!  Beechwood set, made in Sweden, used by my son as a toddler and beyond. Suggested age range is 3-10 years. 
The track sections and painted engine + 3 cars are clean and whole, with no broken parts, chipped connections, or split sections... though one only of the curved sections has some red paint splashed onto it.  The overpass and pylons are whole and intact, and all originally included pieces are included: 10 straight track sections (6 long and 4 short), 12 curves (6 left connect and 6 right connect), 2 overpass inclines and two pylons = 26 track pieces plus the engine and three cars, plus the Tunnel, are ready for another 40 years of play!
The large box shows plenty of wear, but is not torn or crushed, and is still quite clean inside... there is no separator insert with this set, no manual or catalogue (if those were part of the original packaging... just guessing here.).  The Tunnel box shows minimal wear, and is also intact.  The parts are currently well separated and padded inside the box, including the Tunnel, with plenty of reinforcement outside as part of the packaging.
eBay will handle the payment arrangements, and I will post feedback once payment is confirmed.  
I'll post in a Priority Large Flat Rate Box (game size) for $22.80 domestically.  The package is ready to ship today!  
Thanks for looking!  There are several other items listed on my account... please have a look!
