The crystal cans actually don't really drift if they're within their operating temperature range, that's probably hotter and colder than they'll ever be in your locomotive. The large chips are memory and processor, you're not really thinking of trying to replace those, are you? #6 is the relay without it's cover, it should be a black plastic square.
That's kind of how I read it too John. No, no chance of changing the large chips, that's for sure. I was just curious what they might be. I figured memory and the main cpu. Thanks.
