What did you do to your trains today?

I found it a lot easier modifying Salty than Dennis because of the odd angle front of Dennis. In fact I find my "Menace" is one of my least favorite work of all my customs and might revisit him in the future. On the other hand, my "Salt Substitute" (green Salty) is one of my favorites. Tramp also has a custom red Salty which had inspired me.

I appreciate the advice and it sounds like my initial assessment of these engines as well. Salty's flat, multi-part front and rear seem to offer so many customizing possibilities. With Dennis, I feel like a custom toy version of the South Park Underpants Gnomes: 1- Deface; 2- ????; 3- Custom!
