Click the bus for the audio. Sorry if there's too much background noise since it was raining (I had an umbrella with me to protect myself and my phone though), but at least you can still hear the engine and the exhaust note. I decided to test out my new phone's camera since I can zoom in more to see the bus closer on it compared to my old phone though, so I was trying to wait for this one DT408 engine-swapped FS-65 to test my phone's camera out, but I see a 2005 Thomas FS-65 with an MBE906 engine instead, and since the engine didn't sound like a DT408, I decided to look at the bus's specs and it was actually from a local area rather than a different state, so I think that bus (which was recently retired and sold) replaced the DT408-swapped FS-65.
