Narrative:
Air carrier X was in position and holding runway 18R when takeoff clearance 'fly straight out cleared for takeoff' was received. Assigned initial altitude 2000 ft on the keene 2 SID. Upon leveling at 2000 ft MSL. TCASII gave a RA to climb. Tower gave a heading of 240 degrees the same as on the SID. Conflicting traffic Y was taking off runway 18L. The amount of traffic was the 'normal' dfw of short delays. We were given non standard taxi instruction to cross the runway 18L and taxi to runway 18R. We were unable to determine the reason for non standard procedures, so we did not question the non standard takeoff instruction. At the time of receiving the non standard taxi instructions we discussed the possibility of controller training taking place at the time.

Title: ACR X TCASII RA WITH ACFT OFF PARALLEL RWY HAD NMAC LTSS. SYS ERROR. EVASIVE ACTION CLB.
Narrative: ACR X WAS IN POS AND HOLDING RWY 18R WHEN TKOF CLRNC 'FLY STRAIGHT OUT CLRED FOR TKOF' WAS RECEIVED. ASSIGNED INITIAL ALT 2000 FT ON THE KEENE 2 SID. UPON LEVELING AT 2000 FT MSL. TCASII GAVE A RA TO CLB. TWR GAVE A HDG OF 240 DEGS THE SAME AS ON THE SID. CONFLICTING TFC Y WAS TAKING OFF RWY 18L. THE AMOUNT OF TFC WAS THE 'NORMAL' DFW OF SHORT DELAYS. WE WERE GIVEN NON STANDARD TAXI INSTRUCTION TO CROSS THE RWY 18L AND TAXI TO RWY 18R. WE WERE UNABLE TO DETERMINE THE REASON FOR NON STANDARD PROCS, SO WE DID NOT QUESTION THE NON STANDARD TKOF INSTRUCTION. AT THE TIME OF RECEIVING THE NON STANDARD TAXI INSTRUCTIONS WE DISCUSSED THE POSSIBILITY OF CTLR TRAINING TAKING PLACE AT THE TIME.
