Most, but not all, DCC systems can run one DC train at a time along with the DCC trains.
You will eventually want to install decoders in the DC trains.

I rarely run a DC loco with a DCC loco, but it can be done....the DC loco will heat up faster, will run hotter and make growling noises at idle. It's sure not something I do or would recommend for long periods of time.

Older Fleischmann locos can be really hard to install DCC in.
It is due to the fact that they have live chassis and it is hard to isolate the poles on the motor, BUT it can be done!
I have done a few myself, if you use a multimeter to check your work it´s fine.
Good luck.

If I remember right, they have 14v bulbs in them so they should work without any changes. Most DCC systems put about 14-16v on the track. If the lights a very bright you might have to change the bulbs to higher voltage ones or put resistors in each car.
The advantage of DCC is that light will always be at a constant brightness.
The disadvantage of DCC is they'll always be on unless you put switches in every car or park them on a track that can be switched off.
