When I started you changed the WTT and it took a week to appear downstream. There wasn't as much change and churn then. Nowadays I click publish and it's downstream the next day, or as I discovered a few months back the same day in some systems. With modern communication we can phone up or email signallers and advise them of changes. I did print off a physical individual schedule yesterday (F3 for those who know) and that's the first time I'd done that in months.
Most people now want a PIF or CIF for their system, or signallers interrogate TRUST or their own simplifiers. That said if I touch a station where we do the workings I will see the daily workings for the rest of the week are amended and reissued along with base workings updated. Not doing that can lead to interesting conversations.
Last time I saw a printed WTT it was propping a door open.
