Facility info

OPERATIONS Strict appointment-only facility. Opens 4am (gate actually opens ~4:15am). Receiving window 4am-9am. Check-in with S/R on front side for dock assignment. Must have EFS or Comchek ready — lumper fees are CST Diamond, not prepaid. Gate requires yard dog to open. Unload time typically 2-4 hours, sometimes 5-6 hours. Will hold reefer loads over weekend and refuse early Friday deliveries. Occasional returns and damaged freight. PARKING & FACILITIES Minimal overnight parking: 2-3 spots along driveway/street. Tight backing space at front dock; rear yard has more room. Unisex restroom available inside during day. No porta john. No restroom access at night. LUMPER FEES High — consistently $600-$1,700+ reported. One driver paid $1,700 (more than double typical OTR rates). Fees must be paid before dock clamp releases. System backlog causes significant delays between check-in and lumper assignment (up to 5+ hours). STAFF & FACILITY ATTITUDE Mixed. Some drivers report friendly, professional staff and good service. Others report rude, dismissive employees and poor communication. Yard conditions vary by section — front tighter than rear. Driver parking behavior and lot management inconsistent. OTHER Also known as CST. Some facility drivers observed parking inconsiderately and driving dangerously (ignoring signs). Wrong items sent multiple times. Staff occasionally apologetic about long wait times but delays are chronic.
