Sorry ladies, with the Holidays and everything else going on I ended up getting ill and am having a horrible time getting over it. Now tonite hubby has come down with it too. We make for a miserable pair!
The train cars in the video seem quite long to me and if a world builder does not come on board it would be a moot point. But there is a mod that you can use to make any size lot (like a 15 x 25 or 30). I believe in CAW you can make what size lot you want also. It's just a thought and we would need a world builder to pull off the different lot sizes unless everyone had the mod to make their own lot.
With sims I prefer a playable lot so routing over realistic for me.
