Drive until train couples to another consist on the way in DCC mode. The train stops immediately after coupling. You may need to use SetDCCThrottle or SetDCCSpeed (along with SetMaxDCCSpeed command) commands to adjust the speed of the train before coupling.
NOTES: This command is identical to 'TCouple' command used in TRS2004 and replaces TCouple in TRS2006. In this update only the name has changed.
