Norton posted:If Lionel is using plastic for these steps it may be Delrin or a similar plastic. Stryene would break way too easily. If it is Delrin solvent cement won't work. Put a drop on it to make sure. If its Delrin the solvent will just evaporate off without melting the plastic.
In that case CA, super glue, is likely the best choice. Contact cement like Goo or Plyobond will work too.
Really does depend on what plastic the parts are made from - steps and where they attach. If styrene then a solvent cement specific to styrene would work. Same if both are ABS. But Delrin is another beast and solvent cements generally fail. CA sort of works for Delrin particularly if you can rough up the surface to give it some tooth for the CA to grab into. Otherwise, a contact cement such as Goo or Pliobond will be a better choice for attaching such parts. Another reason for using the latter 2 is that the bond remains somewhat flexible and these parts tend to take a bit of knocking about over time and that flex tends to tolerate that handling. Using CA and solvent cements are oft times unforgiving.
