Body: <p>Looking for more info on circuit board of 28743. E.g. what is the processor used? Would like to be able to reprogram the chip. E.g. program the train to stop on the third STOP directive strip, or reverse the train direction if it immediately follows a TOOT directive strip. Ultimately I'd like to program it from Scratch or Python code, but that may be asking too much.</p>
