A Product Review Of the
Battery DANNY Locomotive.
Danny is a very simple
0-4-0 locomotive built entirely of metal. She's heavy, even without the battery
pack, and feels very solid. More like a simple live steamer than anything else
in fact. The body outline follows no particular prototype and even in this
respect, some aspects are more akin to a steam locomotive - particularly in the
cab area. There's very little detail supplied but it can (and in my case,
will) be added very easily. This, no doubt, accounts for the shelf price
of just £195.
Traction is supplied by a small 12v motor, driving one
axle through a reduction gearbox and crown gearwheel. It's a bit exposed so take
care that the loco doesn't drop into the dirt - even so cleaning up is pretty
easy. The drive is taken to the other axle through connecting rods. This works
effectively to provide plenty of traction within the limitation of the small
motor. With the weight of the loco, slipping doesn't seem to be an issue:
however the motor will stall if it can't cope.

As you can see from the
previous picture the front grill is probably the naffest bit of the whole
design. However, it's going to be simple - even for me - to correct with a black
plasticard inlay. One thing you don't have to worry about with a battery loco is
heat. Now let's have a look at the works with the body off. The body is one
piece and is removed by the simple expedient of unscrewing the brass exhaust
pipe. The battery pack is not included with the loco (although the holder
is) and can be purchased at the same time for an additional £15 or so.
This includes an intelligent charger and 8 AA NmH cells, so is something of an
essential bargain. You could use your own batteries but this does make life
easier. Running time on a full charge can be measured in hours.

The locomotive comes ready
to run apart from charging the batteries. An overnight charge is recommended -
don't be tempted to run with the batteries half charged initially as
disappointment will result. The big advantage with NmH cells is that they have
no memory effect so a part charge won't actually harm them - just that Danny
won't perform at her best.
The control panel (!) as shown
contains an on/off switch, a direction switch, and a "volume control" -
throttle.
Underneath you can see how the motor is mated to the drive -
again very simple but effective. The motor proudly displays its' parentage as
Como Drills!

As supplied the wheels are
gauged to 32mm - which I would guess would suit this little loco very well.
However regauging is easy with the supplied Allen key which fits grub screws on
the wheels - they supply a few spare grub screws as well. Be careful here to get
the gauging spot on as otherwise you'll have problems with LGB point work.
Fortunately there are no problems with quartering as the rods are connected to
the outside fly cranks and don't need to be touched to regauge. Make sure that
you keep the wheels centred on the axle. I used a Roundhouse back-to-back gauge
which I have, but it can be done by eye (I would suggest that a simple
wood back to back gauge may be useful, which can be made using an LGB wheel set
to give the essential dimensions). The flange depth of Danny's wheels are
much less than the LGB "hold onto everything at 120mph" variety, but even so
this shouldn't cause any problems unless your permanent way is well past its'
sell by date. In which case a spot of relaying will be in order
anyway.
The wheels are not insulated, so give up any notions of running
Danny whilst you have power in the rails; it just isn't going to
happen.
So how does it go? At
first I was a little disappointed as the loco seemed to make a lot of noise and
have insufficient oomph. However I hadn't given the batteries a full charge in
my impatience (see above!). An overnight charge, a spot of light
oiling, and careful running in for a couple of hours has resulted in a dramatic
improvement.
Even so, Danny doesn't run with the accustomed silence that
we expect from an LGB loco. The motor and gearbox emits something of a banshee
wail whilst under load, though even this is now starting to diminish.
As
you can see from this pic the other feature that needs some work is the back of
the loco. This is designed to ease access to the "regulator" which it achieves
until you couple a coach on the back. Again, this will be replaced by a cheap
and simple plasticard overlay more in keeping with this type of loco.

Although I may seem
critical of this loco, don't be misled. Actually I am very impressed. She
(it seems funny calling a loco named Danny "she" - must be
Danielle!) is starting to perform really well. OK, not in the league of
the big locos, but Danny will potter along happily for hours with a short string
of wagons....

.... or a couple of
coaches. As an introduction to battery control, she's all the better by coming
ready to put on the rails and go - not a sniff of ability to build is required.
She performs like a prototype of her size and power, and it's great to be able
to run to run a train on filthy (but clear of obstacles) track at
a whim.

The only real criticism I
have is that really naff front grill! Otherwise I think that Danny has all the
makings of "a really useful engine"!
