Both the trains stop inside the tunnel. Question does not state that the trains come out of the tunnel

That's two different Tunnels because its not mentioned train enters in same Tunnel.

They travel at different times

There is a tunnel. Inside is only one train track. A train comes in from the left at 2:00 and another train comes in from the right on the same track at 2:00 also. Both come out safely.
