- Feb 5, 2010Hi Garth etal,
This is a very cute and nicely detailed steamer.
Here is my first assessment:
I have used hand calipers to measure the gauge width of
the Tenshodo D51 Mikado vs the Marklin Mikado.
These are first measurements with a Mitutoyo Digital
caliper and without the benefit of a large Optical Comparator.
(So your measurements may vary).
1] There is a difference in Gauge:
D51 = .243", (6,17 mm)
Marklin Mikado = .249" (6,32 mm).
2] Wheel Flange depth:
D51 = .020", (0,51 mm)
Marklin Mikado = .030", (0,76 mm).
I will test run the D51 through MTL roadbed track later this
week when I have the time. So performance is not yet
a part of this impression.
Peculiar looking Arnold style couplers that are scaled down
from the standard N scale type. (Neither Marklin or MTL type).
Overall, a very likable little steamer. Looks like it belongs more
in the 1/240 scale realm of choo-choos though and that might be
an odd place to aim for. We'll see after the operations tests.
