I don't think I have seen a Fenbo EuroStar before. Are you sure its Fenbo, it looks like the trains that Nigels was collecting that had gray track with round connectors. I can't remember what those were called so maybe they were called Fenbo. Could they also be in the Kansai (spelling?) range? I will look on the Auctions of Japan.
Ok...determined It can't be the sets Nigels was collecting as they were middle car powered.
