Numbering of trains based on their Respective zones & Divisions:
The first digit
In the 5-digit train numbering scheme, the first digit indicates the type of the passenger train, as follows:
0 is for special trains (e.g., summer specials, holiday specials, etc.)
1...
more... is for all long-distance trains, including the Rajdhani, Shatabdi, Jan Sadharan, Sampark Kranti, Garib Rath, Duronto, and other classes.
2 is also for long-distance trains; it is to be used when train numbers starting with 1 are exhausted in any series.
3 is for Kolkata suburban trains.
4 is for suburban trains in Chennai, New Delhi, Secunderabad, and other metropolitan areas.
5 is for passenger trains with conventional coaches
6 is for MEMU trains
7 is for DMU (DEMU) and railcar services.
8 is currently reserved
9 is for Mumbai area suburban trains

Second and later digits
The significance of the second and later digits depends on what the first digit is. Below, the different number series are explained, based on the first digit.
0, 1, 2: In the case of special trains, and long-distance express trains, i.e., trains starting with digits '0', '1', or '2', the remaining 4 digits signify the railway zone and division exactly as in the pre-2011 4-digit scheme. In fact, most 5-digit numbers for long-distance trains as of this writing [4/11] are created simply by prefixing '1' to the former 4-digit codes. See below for an explanation of the 4-digit system. The zonal codes (second digit) are shown below:
0 is for Konkan Railway
1 is for CR, WCR and NCR(?)
2 is for superfasts, Shatabdi, Jan Shatabdi, and some other classes of trains regardless of zones. For these, the next digit is usually the zone code.
3 is shared by ER and ECR
4 is for NR, NCR and NWR
5 is shared by NER and NFR
6 is for SR and SWR
7 is shared by SCR and SWR
8 is for SER and ECoR
9 is for WR, NWR and WCR
