So that was two connections, and it's still two connections.
Leave London late morning on Eurostar changing in Brussels and Koln, into Berlin for 9pm or so.
If you'd rather do it with an overnight sleeper leg in, again it's possible on a 2 change basis but admittedly you need to walk from Paris Nord to Paris Est.
www.bahn.de is a good place for pan european train schedules. It does show a couple of Dublin-Berlin options that take around 23hrs, although some of the connections look slightly circumspect - as I say, it's a start...
