Thanks guys. Here's another of the diversion channels with little bridge. There will be many more thanks to the saturated subgrade.

And here is where the excavator broke through, sank and spent several hours digging itself out.  Having waited several months for the ground to start drying, I gingerly crept up to the edge and dug down, finding hard clay 2 feet down.  Once I work out where to put the slop, I will venture back in and open the trench out to become a deep drain.
Pete

A break from rain so back into the "breach"
From the pic above, a major change of route is being planned, more later.
Further down, in the swamp, less moves possible as I'm right on the boundary fence.  A lot of water comes in from the neighbour property.
This is the "flood" pic

I'm going to keep the old alignment as a drain. Dig out when no further access required.    
Raise the track by about a foot.  
Make a barrier on the boundary to reduce inflow.
Dig a land drain to lower the water table.
Find a new way of getting to this point by train
 
A layer of roadbase helps reduce the sinking.
This is the same view as of today

And from the other direction.. note the yellow markers disappearing into the scrub for probable future alignment

Hi Pete
 
I modelled the S's - that was tuff....
 
I have made an E-drawing that you can find here: https://dl.dropbox.com/u/64541328/Verande_end.EPRT
 
All rings and S's are 2mm & the bars are 4mm. I have worked hard to avoid zero thickens there circles and bars meet.

 
 
Finally got the file converted and sent to the laser people.  Got the result today and it's  AWESOME   I'll have to get back to work on the coach again.
Thanks a million, Steen.    Pete

While we have the carriage progress, I got a chance to test the new brake system in earnest, hauling 8 passengers at a track with a long steep grade.
The installation takes up underseat space of 14" x 9" and operates by remote control (garage door button) from the loco. The cattle cars are also linked by a selectable train valve.  Whilst it can't do a low pressure application (its either on or off)  a quick stab on the button knocks off excessive speed and becomes quite controllable with practice.
A sound module activated by a mercury switch, lets rip with "stampeding cow noises" if the train jolts. It proved very popular with the crowd (along with the warning that any kid who misbehaved would be end up as hamburgers)

And further down in the depths of the swamp... A friend laughingly suggested use tree trunks laid as cordouroy, like they did in the old days.
Since the area is not drying out, I figured I had nothing to lose.  It worked!
A bed of logs gets the digger into the spot, and the slop is dug out to make a drain, and laid on top where it dries like concrete. Here I had to negotiate a tree, so the logs were put under the machine, then moved to the RoW as it progessed.

The same cordouroy road bed ready for grading and base course. (I'll do it later, but now at least its not weather sensitive).  The drain has lowered the water table almost immediately.
Meanwhile the next station (Forsayth) is ready for track, requiring a  passing loop, works siding and the relocated turntable

Pete, nice use of small trees.  Are you sure the wet weather won't change the roadbed to a soopy mix when it rains hard and long?  Is the Mud/dirt really good for the sub-base?

Yes
 
 
 
Well I think so
 
 
 
Maybe
 
 
 
Ok, it's sand not clay (mud) so its only slop when the tide comes in. Provided the water table is kept low then its as strong as a sand castle. Pete

No 3 switch just arrived by Jamaican Bobsled wagon.
