Measure twice. cut once...
I have had trains for a very long time but haven't had a layout since I was 12 or so.
I recently started a lay out.
My plan was to have a 4x8 with another 4x8 in an L formation.
This Table would have left me with about 1' clearance to squeeze by a wall.
I measured and figured I could go to a 3' table for my L but when I started laying track... it was 2 short to complete a loop. I had to make a triangle addition to butt into the corner of the 2 tables.
Anyway. if i had measured twice before cuting I would have possibly seen my mistake...
haha, you described my exact layout, and no kidding I had the exact same issue. For some reason I thought I could make that turn in and make it out again within the four feet.
I also added the small triangle at the inside of the "L". I don't really think of this as a mistake, more of an "adjustment". It doesn't look to bad.
My biggest lesson learned has to do with you essentially get what you pay for in this hobby. I learned to stay away from train set quality "toys". More trouble than the few bucks you might save....
