VSTP

The VSTP (Very Short Term Planning) feed provides train schedules which are due to run in the next 48 hours that aren't included in the SCHEDULE feed.

Message Topics

VSTP messages are available through ActiveMQ.

Topic name	Description
VSTP_ALL	All train schedules which are due to run in the next 48 hours that aren't included in the SCHEDULE feed.

Structure

Messages are sent in JSON format and are broadly similar to the messages in the SCHEDULE feed:

Note: CIF Speed

There is a VSTP process that has been known to populate the CIF_speed field incorrectly. As of April 2024, this appears to have been fixed.

For reference, the following speed values should be divided by 2.24 to get miles per hour:

CIF_speed value	Speed in mph
22	10
34	15
56	20
67	30
78	35
89	40
101	45
112	50
123	55
134	60
157	70
168	75
179	80
195	87
201	90
213	95
224	100
246	110
280	125
314	140
417	186
