14.2 Finescale comments By Nigel Brown
One thing to watch is that different locos have different limits. If
you've got some locos which you intend to use on the layout I'd suggest
sticking a bit of the track (I find an 18" length enough) down at the
minimum radius you're thinking off and seeing how it goes.
I used a pannier. I've since
tried some others. The results on the 25.6" radius plain track are:-
8750 0-6-0T pannier (what I tried before) fine
57xx 0-6-0T pannier (this has one axle slightly over gauge) fine, if
tighter, goes better one way (the over gauge axle may also be slightly
misaligned)
42xx 2-8-0T goes round the curve, but jerkily, obviously too tight.
Also, the couplings on the ends are too far out to engage properly,
because of the locomotive length.
58XX 0-4-2T goes round the curve, but rather tight.
517 0-4-2T as the 58XX (this currently has other problems, mainly
pickup reliability)
2151 0-6-0 Collett goods goes round the curve but tight (loco and
tender). Also tender rammed up against loco; gap would need to be larger
78xx 4-6-0 Manor not a chance
On the 32" radius track with a Y point, all were OK on the plain bit,
except the odd pony wheel shorting on the Manor (known problem, waiting
to be fixed). On the Y point:-
8750 fine
57XX bit bumpy due to overgauge axle but basically OK
42XX problem with pony truck if leading from toe of point
58XX similar problem with rear truck
517 as above
2151 OK
Manor OK apart from occasional shorts
So basically I'd say that a pannier or similar 0-6-0T is OK on this
sharp stuff but a lot of others would have problems.
