Grot Train Robbery - Possible Table Layout 1

I'm struggling with a layout that I like. I've run out of straight sections of track and I'm not quite sure where to get them locally by Saturday. All the track I have is from 25+ years ago. I know it is still available, just where? The lack of track means I need to orientate the boards side to side (long sides touching) instead of end to end. So this makes the layout about 8 x 12. Anyway, here are some pictures of layout 1.

Train Start

Here is a view from the side the train starts. As one can see,  I need texture the boards. I need to use the track cross piece as I ran out of straights. I could do more curves there instead, but I wanted the train to start in the middle. Still, that will change.

Ash Wastes Section

The table is made up of three sections. The first section is the Ash Wastes section. I'll be adding in some rough ash wastes terrain pieces and outcroppings to make this a bit more interesting. 

Junk Town Section

The middle section is the Junk Town section. One can see the Junk Town at the top of the picture. Near Junk Town the Imperial defensive wall has been breached allowing entrance into the ruined city. The bottom half of the board contains old imperial defenses and the gateway into the ruined city the Imperial train uses. There will be tank traps here as indicated by the boxes of...tank traps.

Imperial City Section

This last section is made up of a ruined imperial buildings and the wall fortification. With the board needing texture, as with all of the buildings, it looks pretty shabby right now. Most of the buildings are past the prime and 1st stage of painting. But I need to get lots of rubble. Rubble is key to ruined buildings looking 'right.' As I stated last year in my junk town articles, texture and detail are key to making terrain look good. Rubble handles both of those jobs with ruins.

Train End

Here is the end shot of the imperial city...pretty shoddy. Still lots of work to do on terrain and I have to paint the Train! Ugh. At least all the Grots are painted and 90% of the trukks are done.  And the question remains, do I look to get more straight sections of track. I've got a nifty idea of having part of the route go through a destoryed Imperial Tank factory. (In the past, the train entered the factory empty and left the factory loaded with Leman Russ tanks with the train never stopping. I pictured it with the Leman Russ tanks being built right on the train as it went through the factory. Not practical but fun.) I just love the idea of Grots swinging down on chains trying to board the train.
