It's too easy, isn't it? Still, I find it fascinating; a smooth, quiet running Dapol Class 50 was a pre-owned bargain and another piece of luck enabled a body-swap to pre-TOPS Blue, just like I remember tearing past the swings and slides at our Rec'. I'm now in the habit of using Digitrains sound files, but they didn't have a Zimo Next18 small enough at the time. I nearly went with Legomanbiffo as his projects are sublime, but didn't want to confuse myself with ESU and Zimo protocols! Luckily Youchoos had the hardware and Digitrains did a reblow.

And here it is on speed step 4 with volume at 40/255, turn the volume up and enjoy.
