Wouldn't be the first time someone did this... For years trains arriving at London Victoria and a few other stations where the concourse was too well covered took 30+ seconds to open the doors because the driver had to override safety systems to unlock the doors after a new system was put in place that automated which doors to open based on GPS location (there's a lot of variation in how long the stations are, and some long distance trains will operate with up to 12 carriages even though they may stop at stations with space for possibly as little as 4 on the platform, and the platform may be on either side)
