I think this suggestion should be at civilian discussion and train driver is a side mission just like butcher so it shouldn't be added on /stats and even if it gets added it would be converted into a civilian job and removed from side missions and if this gets added then butcher would have to be added too and /stats is already too big so adding more would make it a mess
Apparently you posted this reply without checking from the accuracy of your info. Train driver is a job(Beta job) , as far I know it doesn't have any achievement for reaching level 10 in it though . It has been developed by nikos to be a job not a side mission so comparing it with butcher and street cleaner side missions is a mistake. I think the only excuse of not adding it to stats is being not full developed since many bugs are not completely fixed yet. Train driver job deserves to be listed in civilian ranks section
