Add detailed to the end of your query - it'll only search freight and charters if you're in a detailed mode page. e.g. "5Q23 detailed"
.... I discovered that the hard way (in other words,
eventually by trying it) but I am not complaining and I like and value RTT and appreciate it is complex and so has limitations.
Those limitations are largely controlled by the rail network not updating train movements quickly enough rather than RTT being at fault. A very typical example are the yellow Test Trains whose timetables can vary very wildly and of course engineering trains etc - Anything yellow!
I rely on railway insider friends feeding me the headcodes of trains they know I will be interested in shooting. Otherwise I select a spot (as if starting there) and do a RTT detailed search with a custom timeframe and then select individual trains from the list it loads. Entering ZZ narrows it down to freight and engineering by omitting all the standard passenger train stuff. Sometimes RTT doesn't load a headcode directly via Detailed Search but does show it in the list I have just described.
Consequently I am seeking an
additional app to be able to see a train's
live progress towards me and my camera on a signal by signal section basis. It must be iOS (Mac) friendly. I don't think that RTT offer an app so I use my Safari browser.
Traksy looks the best so far and so a one month trial (paid) looks worth it. Others such as OTT and Signal Maps look a nightmare due to no filters and a black background on a mobile phone.
