I just got my first MTH DCS PS2 loco but as a true battery-fan 
I run a dead-track railroad. so to get all the bells, whistles and other noises, and allow full programmability of sound volumes and so on, I installed an MTH Track Interface Unit (TIU) in a box car.
It just fits in a 1/29 box car. I have glued guides to the floor and roof to keep it in place.
and on one side is a power switch and fuse.
I use flat cars and similar to keep the 1/29 boxcars away from the 1/32 tender! Several of my cars have 'thru-wiring' so I don't have the same battery cars next to the locos. The battery car for the train above is in fact off the picture to the left, and the TIU is in the blue stock car. From the 4.5Ah battery I get 2.5+ hours Challenger runtime with sound and lights, including about 30mins of smoke.
I lengthened the antennas on both TX/RX as per help on Raymond Manley's pages and it all works great. Many thanks to Ray for his help with the loco last year to get it running smooth. The only sound I heard before was in H0 scale and I wasn't impressed with the weedy sound there. These bigger speakers sure help. I'm diggin' this DCS sound, I put my deposit down for a triplex /DesktopModules/NTForums/themes/mls/emoticons/whistling.gif but don't tell household management.
