Hello everybody,
a couple of years back I broke a railing on one of my Kato engines. Tried different glues but no luck. Then recently purchased a bottle of ZAP-A-GAP. It did it. It has managed to glue the railings together again. I find it is a very good general purpose glue that works on a lot of different applications. Here is a site that sells it and gives you an idea about the product: http://www.flyfishusa.com/fly-tying/zap-a-gap.htm
Hope it helps.
