Hi Keven
yes because it's GSWR and the difference is a hand built metal bodied 0-6-0 chassis should run much better than a 4-4-0 in 00 gauge due to weight balance, electrical pickup, and driving wheels, which seemed problematic for the 4-4-0 out of the box until some folk modified them retrospectively. That 4-4-0 was a beautiful looking model and I vowed then if they ever produced an 0-6-0 I'd get one. DCC frequency pulsing should compensate for the lack of a flywheel.
The GSWR 101 was such a numerous example of the Irish steam era. Imagine the pic of 184 above in its original all over grimey grey livery hauling green or crimson coaches, with DCC steam sound. You know me Kevin, if a loco doesn't drive well, accelerate and decelerate prototypically, and run smoothly at ultra low speed I couldn't care less how well or detailed it looks. Prototypical function over form every time for me. Personally I 'play' and drive model trains around a layout, not look at them in a display case, and I accept that's just my personal preference, not right nor wrong, just me.
Good night.
