I seem to remember when using high speed rail track a long time ago the speed of the cart that was defined by the high speed booster track/ transition track was kept constant until it was reduced at the other end of the h.s track, but now it seems the speed reduces as you are moving along the h.s track. I've tried putting booster/transition track along the way but it just blows up. Was this changed recently by CovertJaguar or am I doing something wrong, also if it has been changed could someone tell me how to remedy the situation, any help would be appreciated, thanks
