I bought my example of the Adam radial tank from my local dealer in Kidderminster, along with a DCC chip to go with the loco, a few days before Christmas. A present to myself.
Get it home and run it in DC mode - the maximum it will run is at a scale walking space. Maybe it's because it's in DC mode, think I.
Take off the body to fit the chip, and spend the next hour trying without success to fit the chip, plug and harness into the small space available in the bunker. Run the loco without the body and still it goes no faster than a scale walking pace. So back to the shop with loco and chip to exchange both.
Off home I went with a replacement loco and DCC chip which plugs directly into the holder without a harness and it fits perfectly. Put the loco on the track, still numbered 03, and it makes a noise, moves forward six inches, stops, and refuses to move any more, never more to run on my layout.
Take the replacement loco back to the shop and proprietor Derek promises to take to home to get it sorted out.
Fast forward three days and go back to the shop. Derek tells me it has blown three chips, which he puts down to faulty soldering on the chip holder. He's hot wired the chip into the loco and it's working. Take it home again, place it on the layout, it moves forward, stops, and refuses to budge again.
Take it back again to the shop and swap it for a Bachmann E4, which runs perfectly.
I'll wait for Hornby to bring out their Radial Tank.
