Shuppo/good Western train

I have a question regarding the Tomy Shuppo/ good Western locomotive. It is possible to buy parts for these, or not?

From a used lots yes. From the manufacturer no.

[Super]

Wouldn't it be fantastic if a shop somewhere in Japan discovered boxes and boxes fill with new old stock of Plarail parts that were packaged for sale?

Shuppo, is it just the battery cover the part you are missing?

The battery cover is missing. But the funnel and left cylinder have broken off

You can easily use the smokestack body part mold from a Benkie or Yoshitsune as a perfect replacement...
The battery cover from a red Mickey/ Disney Western R/R will work, though the "lock in" tabs are a slight bit shorter...
But the broken cylinder slot attached to the cowcatcher can only be found in black (from the Benkie and Yoshitsune)
The only other way to replace that part would be to send the black one to a 3D printing company and have one created in red
