I have track powered steam engines from AML ( K-4 Pacific). USA Trains (Hudson) and LGB (Mikado). All have an electrical connector between the engine and tender. I find it is relatively easy to insert the connectors but nearly impossible to remove them. They fit tightly and there is little to grab onto when removing them. I am looking for ideas here. One thought was to coat the outside of the plug with a grease that would not harm the plastic. Help please.
