Can activity code is N pick up passenger?

[Dean Zhong]

Hi Team,

I am writing to inquire about the activity code 'N', which is described as 'Stop not advertised'. Could you please clarify whether passengers are allowed to board at a station when this code is in effect? 

Additionally, I would like to confirm if the current activity codes for boarding and alighting passengers remain consistent with the information provided in this post:

Thank you for your assistance. I look forward to your response.

Regard,

Passengers cannot board or alight at an N stop.

As I said back in 2020...

Passenger Activity Codes for advertised stops...

T = Stops to pick up and set down passengers

D = Stops to set down passengers only

U = Stops to pick up passengers only

R = Request stop

There can be up to six activity codes at each timing point. Where one of the activities is an advertised passenger stop then that should be the firstcode in the list.

N.B. Don't get the above confused with -T, -U or -D. These refer to the pick up or set down of coaches and have no bearing on the passenger activity.

For passenger trains, at the origin location the TB, by default, will indicate an advertised passenger activity unless there is a supplementary N (non-advertised), S (staff stop) or possibly OP (other operating purposes) activity. Similarly for TF at the terminating location.
