soldering issues

Ok, so I am a little embarrassed to have to ask this but I cant figure this out so I thought I would come to the experts (I even took a soldering class!).

I have been adding lights to some trains.  (Thanks Super for the black silicone 'hack') I have found that there are just some pieces of metal inside the trains that I cant get my solder to stick to.  I am not sure if it is my type of solder? is it that its just a type of metal that solder wont stick to? is there a coating on the metal that doesnt allow the solder to adhere to the metal.

Cheers y'all!

Can you post a pic of the solder you are using and the soldering iron? In my expierence the cheaper soldering irons just burn up and don’t work too well after a few times.

I've always had problems with soldering until recent times, as Ripley says solder has a lot to say same with soldering iron. I use this kind of solder.
