It can run well with, but it doesn't have to. Some manufacturers write in the manual that you have to remove the capacitor.

The details are difficult to explain in English, please look there: rmweb.co.uk

Tillig also mentions to remove the interference capacitor from the bottom of bedding track 83740 when going from analog to digital operation. Their advanced track system has a separate part number for the DC power connection one with and without the capacitor.

Why is the capacitor incompatible with DCC?
The R/C (resistor/capacitor) network is a noise filter... to prevent motor brush arcing from interfering with nearby electronics (TV, Radio, etc...) These were routinely applied in Europe... and apparently not mandated in the US.

While intended to filter noise originating FROM the motor... the R/C network can also treat the incoming DCC signal as 'noise'... reducing the ability of the decoder to interpret the DCC signal.

I use the removed R/C networks to keep my wastebasket from floating off the floor...

So best to be forewarned - if I unscrew the chassis block are there any loose parts waiting to fall out?

The two halves of the chassis hold the engine and the trucks in place. Because of the wires they cannot fall far, only the cardan shafts are loose.
