If you're looking for a way to clean the motor where the battery goes, you could try cleaning them up by using a Q-tip, put it into white vinegar, and scrub the battery contacts with the Q-tip. Custom Trackmasters has done numerous videos showing the process if you're interested. Back to the subject of the video, I think Plarail did very good at making the Streamliners. Good call to get Caitlin since she's getting replaced by a Thomas variant in the Plarail line.

The Trackmaster versions of Conner and Catlin Look nice despite its flaws and for the Plarail versions, they look accurate to the show, and I really needed those characters someday Same for the king of the railway pack It's pretty interesting that Catlin was Exclusive to that pack and then 3 or 4 they released her in 2018 and I had no idea why this took so long to give her her own release but oh well Overall those 2 streamline engines are amazing.

Hey Wong. I just saw the Custom wooden railway journey beyond sodor engines that you make for keekre and they look great. So I was wondering if you would be happy on possibly making them for me because I’m starting to get into custom making. I can send you all the parts that you’ll need and you can maybe do the rest? It would be nice but I’m just asking thanks. - Caspar
