Just got mine set up and it appears to be going pretty slow. No faster
then any other trains I have seen on the spectrum transformer I need to
put it up to 50% power to even get it to move? Is this normal? I know
people said if you use a different transformer it can make it go
faster. But I thought it woulkd go a little faster then this with the
factory transformer. ANy help is greatly appreciated
No, it won't go faster, unless you can crank up the voltage past 12V,
which I do _not_ recommend. The power pack that comes with the set
produces enough power for the engine to haul its the dummy loco and six
The fact is, those other trains are running too fast. Most model trains
do, so don't sweat it. Don't turn the power packs control knob past
about halfway - that's the setting at which most Bachmann engines run at
50-60 scale mph. That speed will look sl-o-o-ow to you until you get
used to it. :-)
Besides, 150 scale mph doesn't really look all that fast from normal
viewing distances of 2 to 5 ft, or 200 to 500 _scale_ feet. To give you
some idea of scale speed: if it takes one of the Acela cars 1 second to
pass a given point, then it's travelling at around 60 scale mph.
If you've set up the train on its own oval, you have about 14.5 actual
feet of track, or about 1250 scale feet of track. At 150 mph, a vehicle
is travelling at 220 ft/second. So at 150 scale mph, the train should
take close to 6 seconds to circle the oval. If you haven't got a stop
watch, use the "one tugboat, two tugboat" method to estimate the time.
If it's around "6 tugboat" when the train comes around again, it's
running in the right speed range.
Simple number fact to remember: 60 mph = 88 feet per second.
One of the guys in our club has a Bachmann Acela that he brings to run
on our modular layout. He's even added the two additional cars normally
seen in the prototype. Using our normal MRC Controllmaster 2000 power
supplies it regularly runs about 100 smph at full throttle in normal
'DC' mode (regular HO setting of the PS). that's not as fast as the
prototype, but plenty fast on a model railroad!
I suspect the reply above is correct ... you're probably used to seeing
OTHER trains running WAY too fast!
P.S. The Acela actually runs quite well ... it tracks decently even in
'push' mode, at high speed. We were a little apprehensive if this at
first, but it's not proven to be a problem. Perhaps I should add that
our modular layout has 38" radius curves.
One side note. The owner recently installed a DCC decoder in the unit,
and now it only runs about 60 smph full throttle in DCC mode (default
values). He's NOT happy with that. Perhaps he needs to mess with the
'CV' values or some such.
And if you're still worried about duplicating prototype Acela remember
this....the real Acela only does the 150 MPH on straight, tangent track.
So doing 150, even scale 150 is not prototypical on an oval, LOL.
