In my operating plan I run 13 trains per session. The 11-th and 13-th trains are connecting thru trains. The 11-th from staging yard to main yard and the 13-th from main yard back down to staging where the 11-th train came from.  These two trains forever and a day have had only 3 or 4 cars on them. But two earlier in the day connecting thru trains always have between 6 and 9 cars with them.  I sorta recall that Jim mentioned one time that this is not unusual.  Does anybody else recall Jim making this or a similar comment about late in the day trains having fewer cars in them?  I made a paper study a while ago where I tried in earnest to balance the to and from waybills for all my three connecting trains between staging and my on-layout main yard, but I really couldn't get the number of cars in the 11-th and 13-th trains to increase significantly.  Does anybody have an ideas wrt how I can get more cars in these last-in-the session trains?

thanks
