The big question for me is will the power supply included with the Sport Digital sets handle 4 cars with Falcon/TSRF or Slot.It motors? Will we return to the days of cars flying off when another de-slots?

No. You need 2 power supplies for 4-6 cars.

No. Its digital!!!!! Arghhhhhhh!!!!!

It's a question of amps. As it was when we built our 4-lane tracks.

Get the voltage right and make sure you have the right amperage and you'll be fine.

It's an ampacity chain : power supply, control station, contact rails, decoder

The power supply is up to you

Control station/decoder : SCX is limited to the stock motor (in Spain, they immediately fried a decoder with a Slot.it 25k motor) - I would guess the same applies to Scalextric and Carrera - logically, Ninco should provide something more for their NC5/NC6

Contact rails (continuity) : SCX seems OK with the redesigned connectors, Ninco have a good reputation in this respect, I read that Scalextric and Carrera have problems on longer tracks and require power taps/jumpers

Higher ampacity aftermarket electronic packages will no doubt become available in the future (I'm told hardware is not a problem) - I just do not see anything above 25k as being compatible with MCPL racing, the allowable number of cars is more of interest

not so - digital will not mean that the cars get enough current. The chip will try to pass enough, but if its not there, the car will not go so fast. If another car deslots, and there is more current available, it will deslot. So power surges ARE possible with digital - imho.

However, it is also not the case that you can just up the current indefinately. If 6 cars with falcon motors are trying to draw 4 amps each - thats 24 amps - then it could fry some chips or circuitry in the control station, depending on design and the rating of the components chosen. Similarly, 4 amps through the decoder chip may destroy it...

While it may not be worth anything, I agree with XLot. I don't get the feeling that blindingly fast speed would be the thrill for MCPL.

I agree you can use any power supply you want as long as it meets the same requirements the controller station wants. However I don't think using a 25amp 12vdc will work any better that the standard 12vdc @ 2.5amps that Scaley ships with their Digital sets. Forgive me if I got the specs on the Scaley Power Supply wrong.
The circuitry that outputs the DCC will have its own current (amps) limit and it is that section of the controller that would need upgrading in order to handle the extra current draw of a 16D motor. This also assumes the decoder board on the car can handle the current draw of the motor. I'm sure any train guys watching the digital revolution in slot cars are sitting back saying "been there done that and have the scars to prove it"!
Are the digital trains components build in such a way as to let you upgrade or mod sections for better performance?

hmmm... sounds possible... if a car is not getting enough current. depends on how smart the chip is though, huh? fairly trivial for the firmware in the car to ignore power surges, though I am not saying Scaley have done this.
