Hi Tony,
This looks like a Jouef Ireland manufactured set, however the loco and coaches are of European prototypes and are not Irish.
The loco looks to be Belgian, judging by the livery and the coaches look to be of French prototypes, albeit finished in German (DB) and Italian (FS) livery.
The car transporter is of a German prototype.
None of these ever ran in Ireland.
You can get replacement traction tyres on eBay - you just need to measure the wheel diameter so that you get the right size of tyre.
Finally, perhaps the moderators can move Tony’s post and my reply to a more appropriate part of the site.
Cheers
Darius
