Here's a thought - since the DART police seem to having multiple issues. Let's disband them. Since they're effectively unable to police the DART system, let's use the money that they're spending on maintaining a seperate police force to fund some officers in each DART member city and/or deputies in the sherriff's office. This would allow all the money that get's spent on the police chief's salary, his two captains, four leutienants, and various redundant support staff to go to actually hiring officers. This would go a ways toward helping with their shortage of officers. This could be done with little or no increase in cost.
Besides, who can remember to call a special number when you need help from the DART police? Heck, isn't that why we got 911 service? No more special numnbers - you just call and they send help. In an emergency situation, what are the odds that someone is going to think, "Oh, wait...I'm on DART property. I need to call 214-928-6300 and not 911."
