Pierre , thanks so much for your posting !

Yes actually that first posting was a quite poor set up I agree.. The fault was actually more my choices in using the U rail pieces.. ( the esure piece is just 1 piece used for each sid eof the tunnel..) But i have a few more pics to show this  also ..
Tibi has also been helping me build better set ups and also to recall the proper way to us all these peices so you have a more realistic and better functioning above ground road set ups

I constructed a second esure/ U rail set up that uses an under water esure tunnel ...

So first here is a zoomed out shot of one end of the tunnel -




in a closer inspection of the 2 tunnel sides...( there is some improvment here in properly connecting the above ground roads a bit better . Tibi showed me the best way to do this is just to drag out a bit of regular roads first than plop the pieces on top of the existing roads..this worked quite well.. Although really the first piece after the tunnel entrance model should never be a straight u rail road piece really. Because as Pierre points out its a bit un- realistic -







So in the above pic , the surc esure piece is actually the second piece from the end of the cliff. and is a straight orthogonal  piece.. But by using Tibi,s method of having the road dragged prior to plopping down any puzzle pieees  and even with the 90 degree turn that connects into the  the surc road piece , i was able to connect this up to the road system..


So here on the other end of the tunnel side there is even more improvement as the first piece after the tunnel entrance is actually T road U rail piece that is hooked up also to the existing road system.. ( perhaps the use of a 90 degree turn U- rail road piece might be the most realistic to use of all ?)


I am hoping this post clarifies a little better what is the work of the U rail pieces and what is the esure pieces role in these set ups,..and how to use them in a  set up ?
