Here's a question for the history buffs and Postwar and Prewar fans.
Typical story, boy plays with train set around Christmas time - ahh, what wonderful memories; hooking up the frayed wires, smell of ozone, sparks fly, train runs yet again! Was my Marx O-gauge 3-rail track (sadly I no longer have it) the first track system with casted in roadbed? I could not find an internet picture! The usual history is that I grew up with a Marx train set - UP diesel switcher & cars purchased by my father either in late 1950s or early 1960s - and it had neat-looking track with roadbed - black roadbed as I recall...though the color could've been oils soaked in over many years of use.
Was Marx the first company to offer such a neat track system?
