Corridors
We draw a corridor we can describe stop by stop. Bangkok and the trunks that feed it, from counts a client has actually placed on the desk.
A long line. The evening load toward the residential east is the usual reason a desk writes to us. Asok is not a single number. The transfer note has to say which stair and which direction were holding people. We will not collapse the line into one daily total and call it a briefing.
Shorter, and sharper. Sala Daeng and Siam do not share a peak just because both are busy in the same hour. If your file joins them under one interchange code, we split them back or we say on the plate that the file refused the split.
Underground stairs behave differently from an elevated platform. The holds at Sukhumvit and at Si Lom belong in the note as walks between stations, not as a property of either line alone. We write the path only when a count or a supervisor's log supports it.
Often one strong peak rather than an all-day load, with Tao Poon as the joint that matters. A plate that stretches the midday to look more active is a plate we will not sign.
City-bound morning, a thin middle of the day, and Makkasan as its own case. Researchers sometimes arrive with gate totals and no drawing. That is a corridor briefing if the weeks are complete, or a station plate if you only need one stop.
The canal is on this road. Hard rain stops the boats. People wait under the roof or they leave. The next departure that runs can be heavy with the hour that was cancelled. A weekly pier total hides that. We live next to the service, and we still ask you to mark the trips that did not run.
Pier by pier. A commuter pier and a pier that fills with visitors are not the same afternoon. Rain bunches passengers onto the following boat. The 16:40 and the 17:10 can tell opposite stories, and both belong on the page.
School-term mornings toward Lat Krabang and the inner city are the commissions we see most from district desks. A public holiday inside the file will make a Monday look like decline. We mark it on the first plate.
Write anyway if it is in Bangkok or the adjacent provinces and you already hold the counts. We will say whether we know the stops well enough to draw them, or whether you should bring someone who has stood there to the sitting. A line we cannot describe, we do not take.
