Trackmaster front engine couplings

These little doohickeys can be attached to the buffers of some Trackmaster engines to allow putting a hook there without needing to drill into or glue onto the plastic. I had 3 engines to test it on: an old Percy (2009), an old Thomas (2006), and a new Thomas (2016). Each one has slightly different dimensions. I hope one of them works for you. If not, you can customize one of them in the .blend file.
