Problem with BI3 Industry Track - AI Trains not Loading

[TDN-Trainz]

Hi. I am having a problem with the BI3 Industry Track. Following MSGSapper's tutorial on modifying it, I created a track for loading wood pellets (<kuid2:473136:102309:1>). I place speed limits on the entry (6 kph) and duly set up the receiving hopper cars to receive wood pellets. I have set the track to initiate with 10,000,000 of product and a process to produce 1,000 tonnes of pellets. When manually driving a train through the track the wagons load without any problem (speed at 5 kph). However, when an ai train drives over the track (using Drive via Trackmark or Navigate via) nothing happens. The ai train drives at the appropriate speed (varies from 3 to 5 kph).

Can anyone suggest a solution?

BTW I am using Build 132317 on a Mac, if that makes a difference.
