LOL....its not your fault I have no will power Nigels. 
Thank you for the offer, I may take you up on that but first I want to hear more about the bridge when you get yours because the bowstring may or may not work with Plarail. Here is my concern...the measurements seem to be OK but when you take in effect that you take away an 1/8 of an inch on both the top and bottom for the thickness of the MDF I am thinking that because of the curve of the upper bow that those first cross beams may be too low for a Plarail train plus the track so I will look forward to hear about your first hand opinion. Doesn't look like it would take long to build. Now, even if a Plarail train won't fit on the bowstring bridge here is an option....the motorized Plarail/Tomy autos and trucks on the road track. This picture is from the same YouTuber who made the video above showing 2 bowstring bridges back to back used with a road surface. Might work great with the Tomy road tracks.
