DCC mini central with IR remote control for testing locomotive decoders

I just wanted a simle DCC central wich I can use to test new DCC locomotives n ad potentially with a “program” mode so it can “break in” new locomotives for me by running them for specific periods of time in both directions.Β Β  The result is an ArduinoΒ  based DCC central.Β Β Β  It is based on some stuff I picked up from theΒ  “interweb” and either slimmed it down or added new features.Β Β  It uses an ATMel 328Β  microcontroller chip , a 2 line LCD display, some LEDs, a potentiometer , some Pushbuttons and an oldΒ  IRΒ  remote controller from a tv set or video player.Β  The signal from the Arduin o is boosted up by an LMD18200Β  power motor driver chip on a pre built board from ChinaΒ  (8 $)
The schematic below shows the setup.
