I give up on web searches. Hoping some collectors here can help: I've seen Train Robo figures alluded to with "DX", "ST", or "Jr." suffixes, and have seen toys listed that seem more like bigger Kabaya kits than the original Train Robo figures. Were there different (Japanese) releases? Different sizes? Were some (individual pieces) carded and some boxed (individually)? I feel pretty knowledgeable about the Car Robot Diaclones, but I haven't been able to find much English language info or confirmed pics about the Train Robo. Any help is appreciated.
