Narrative:

Air carrier X was flashed and taken prior to air carrier Y flashing from D10; after coordination with dr-2/3 to stop the air carrier X at 160 since FL180 was unusable. With an E145 in front of an MD82; it was clear speeds would need to be assigned. I selected range from nelyn and observed the mit to be approximately 9; with the air carrier Y about to leave 100 and accelerate. I decided to wait for the call from D10 with the assigned speed; when air carrier X checked on with no assigned speed. Shortly after this; with the air carrier Y about 7.5 in trail (D10-ZFW LOA requires assignment and coordination of speeds with 8 NM or less in trail); DR2/3 called me for the hand-off with both aircraft out of 113 and the trailing air carrier Y flight showing a 50-70 knot overtake. I asked the speed assignment; and was met with an incredulous comment asking if I really wanted a speed assigned and with some comment about the air carrier X only going to 160. I responded that I needed separation and yes; I needed a speed assigned in accordance with the LOA. There are several factors here: 1) the LOA requires assigned speeds; neither aircraft had an assigned speed. 2) the radar at D10 updates much more quickly and will reflect speed changes much more quickly than our radar. Several errors over the years have occurred in these scenarios (faster in back with little or no overtake showing) and that is why the requirement was put in the LOA. 3) the D10 controller appeared totally ignorant of our separation requirements. 4) I fail to see any possible positive separation that existed with the two flights both out of 113 for 160 and 170 with no speed assignment; 7.5 mit; and a 1 NM a minute plus overtake. 5) fellow controllers agreed this D10 controller has provided similar service in the past and is prone to shoveling aircraft out the gate haphazardly. Recommendation: training; training; training. Scuttlebutt at ZFW is that D10 is having lots of problems with a green workforce; this seems to reinforce that rumor.

Title: ZFW controller described an overtake event when two successive DFW departures were not issued speed restrictions by D10; the reporter noting D10's propensity to hand off overtake situations.
