BASICALLY I NEED WIDER CURVES AND WIDER BENCH WORK TO ALLOW FOR LONG HEAVY TRAINS. MY WIDEST CURVE IS 041 and SMALLEST IS 031, ALL STEEL TRACK. SO I AM LIMITED BY THE WIDTH OF THE LAYOUT. LIGHTER CARS FROM MENARDS ALLOWS FOR LONGER TRAIN OPERATIONS. AT THIS POINT I AM NOT PLANNING ON WIDENING MY LAYOUT BUT WHO KNOWS. SO I GUESS I WILL BE LISTENING MY TWO LIONEL TANK CARS FROM CARGILL FOODS AND MY TWO AMMONIA PROCOR TANK CARS ON MERCARI. I PAID 60.00 A PIECE AND THEY LITERALLY HAVE MAYBE 10 MINUTES OF TRACK TIME EACH. I GUESS I COULD TAKE THE NEW 4x8 SECTION AND PLACE IT NEXT TO THE ORIGINAL 4x8 WHICH WOULD MAKE AN 8x8 TABLE. I WOULD REMOVE THE 4 FOOT EXTENSION WHERE THE MOUNTAIN IS AND JUST HAVE AN 8x8. THIS WOULD ALLOW FOR LARGER CURVES.
