IRM A Class Bogie Sideframes Loose

[Leyny]

I have a small problem with one of my IRM A Class (A55). Since I got it, the bogie sideframes keep coming loose and falling off. I’m sure it’s something that can easily be fixed but I don’t want to damage the model or leave it that I can’t remove the bogie sideframes if I ever need to. With anything less delicate I’d be inclined to think a dab of clear silicone would do the job but I don’t know if that would be doing more harm than good. Has anyone else had this issue and can anyone advise on the best way to fix it?

A little bit of PVA would hold it and would come off again without doing any damage.
