Adjust your CV2 start voltage:

Settings that I would have (based on other locos on my layout):

CV2 - set to 2 - Minimum Speed (V Min at step 1)
CV5 - set to 120 - Max speed (V High)
CV6 - set to 40 - Acceleration Curve (V Mid)

Remember that with the TCS MC2, you can have 3 acceleration and 3 deceleration rates.

If you want to simplify acceleration (CV3) and deceleration (CV4), you can use a straight line acceleration and deceleration, but using values over 0 in CV125 allows you to set a 3 rate acceleration curve using CV125 to CV128 and a 3 rate deceleration curve using CV129 to CV132. Refer to your decoder manual for a graphical explanation.

What is your DCC system?

That is what should happen. If you decoder is set correctly, then it is probably the decoder itself that is faulty. Try using another one. Don't TCS have a 'goof-proof' warranty?

That's good. Send the bad one back for a replacement.
