I believe dynamic weather should be added as this could be quite interesting such as starting in light rain and mid-way through the weather could to turned on you and become a full-on storm (when they are added (if they are added)). There should also be an option when setting up a timetabled service where you choose your weather to be dynamic or non-dynamic
MSFS has live weather based on location right? That kind of system would be great to have in TSW, as long as DtG have resources for it.
Dynamic Weather sounds good, but reworking the rain would be nice too. When it's raining really hard in TSW and it's also the darkest night and you have to turn the peak light up to full light, you can't see anything but white streaks of rain.
