Latest issue of the SA refers to an automatic "banker failed to detach" message - do the axle counters at the bottom automatically work out that a banker has been attached?

If there are three or more axle counter sections and the banker is known to be starting from one of them should that section remain occupied but the next one go clear behind the train then such a message could be generated but it would also be generated if the section failed at the appropriate moment as well.

It occurs to me now that perhaps the clearance of the sub from the siding tells the system a banker has been attached?

If the train leaves the section without the banker, as it should, then the section should still show occupied. If the banker goes out with the train, as it should not, it should then show clear. A little extra circuitry/software could interpret this to give the required warning.
