Unrecorded Phantom Gems

It is about the ring. It is known as タブレットキャッチャー. However if you translate to English, it is "Tablet Catcher". Chris, is Tablet Catcher the same meaning as token? I'm not good in English.

Exellent, that confirms it. Tokens existed in various different shapes and sizes, one of these was known as a tablet. 

From the Wikipedia entry on Token (railway signalling) : "A large staff could be handed over without any special apparatus, but if the system in use employed miniature staffs, tablets or key tokens, these were usually placed in a leather pouch attached to a hoop, and the fireman could put their arm through the hoop held up by the signalman, and vice versa as the locomotive ran past."

Now your task is to find out whether similar equipment was ever used in the early days of Japanese railways, in which British engineers were heavily involved.

I also want to know whether the Thomas locomotive in that set had any way of holding the tablet ring so that it would be caught by the hook on the station platform as it went past?

By the way your English is just fine, but if you ever want help in preparing an English-language version of the Museum website, just let me know!
