The bridge track is... track, so you have to supply whatever you normally feed to your rails. If you are running digitally you have to provide your normal digital track signal. If analog, you pass in your varied 16V analog power. If you feed power from that Conrad transformer any loco on the turntable will go at full speed. If you are asking about powering the TT-DEC decoder, you answered your own question, it take 16 to 18V and the Conrad transformer supplies 18V. In addition to power, I presume any decoder will also need a digital power input.

Yes but my question is: 18v are for the decoder AND the motor ? The motor is normally powered at 16v.

The TT-DEC supplies the motor, not the power supply, so whatever power supply is allowed for the TT-DEC is suitable for the TT-DEC to drive the motor.

Ok, the TT-DEC is powered with 18v and provide 16v to the motor. I prefer not to burn the engine. So this power supply is appropriate (a little too powerful but I think to use it for other accessories too). Thanks for your help.
