My Marklin #1 gauge track is 40 years old, and the numerical designations have apparently changed. Can anyone please tell me if there is a modern equivalent to the old #5900 straight track and the #5932 curved track (1020 mm radius)? Is the new track completely compatible with the old, or must some sort of transition track section or rail joiner be used? I greatly appreciate any information and advice that forum users can share with me about joining old and new track. Having just gotten my 40 year old Marklin Spur 1 models out of their storage boxes and wanting to build a shelf layout around my workroom walls, I need more track but I'm feeling a bit like the literary character Rip Van Winkle who awakens after a very long sleep to find the world drastically changed! Thank you, Merci, and vielen Dank!

Many thanks. This is extremely helpful, and I greatly appreciate the effort to send it to me!
