Revision as of 15:51, 10 May 2019
General Observations
- always 67 bytes
- exactly for one passenger/leg
- does not seem to contain signatures, checksums or compression, based on minimal bit pattern changes on adjacent tickets
- a lot less null bytes when PNR/seat reservation are present (ie. highspeed train tickets?)
Bit Layout
| Byte:Bit | Content | Meaning | Notes |
|---|---|---|---|
| 0:0 - 4:7 | 0x20 0x14 0xC2 0x08 0x10 | header? | fixed value in all samples |
| 5:0 - 7:7 | date? | varies between samples | |
| 8:0 - 12:7 | null | ||
| 13:0 - 14:3 | 0000 0100 0000 | fixed values in all samples | |
| 14:4 - 17:3 | 24 bit uint | UIC station code of departure | |
| 17:4 - 18:2 | |||
| 18:3 - 21:2 | 24 bit uint | UIC station code of arrival | |
| xx bit uint | train number | ||
| 25:0 - 29:7 | null | ||
| 30:0 - 38:7 | null if no PNR present, seems to contain seat number? | ||
| 39:0 -42:7 | null | ||
| 40:0 - 50:7 | null if no PNR present, unknown content otherwise | ||
| - 62:3 | xx bit uint | ticket number | |
| 63:4 - 65:7 | null | ||
| 66:0 - 66:7 | varies between samples |
