RLGN/RLWL==> it is the same as RLGN.
When you purchase a ticket from PRS, it would be depicted as RLWL, and upon checking the PNR online it would be shown as RLGN.
Some months back I had seen specific quota depicted as RLWL but guess the said process has been discontinued now.
1) RLGN is intermediate-end quota.
2)...
more... Has a share of the general quota/originating station=> Has more number of berths=> Supports RAC.
For some trains, the quota of the intermediate stations is quite low and hence it does not support RAC. In these cases, it is usually depicted as RLWL => Does not support RAC and hence has least chances of confirmation. (However as said earlier, to a lot of people RLGN and RLWL is one and the same. Hence you would need to search whether the station holding this quota has a larger share of it or just a nominal one)

As said by MST Sir here:
/blog/post/30023/6
Assume in Coimbatore Kurla Exp, some berths can be reserved only between Coimbatore and Bangalore. This is called Road side quota (RS quota : start to intermediate).
Some berths (infact the same berths) can be reserved only between Bangalore and Kurla. This is called Remote Location quota (RL quota : intermediate to end).
.
The berths on charts pasted on trains are denoted as "SBC/" and "/SBC" respectively. One cannot book a single berth in these quotas from anywhere in CBE-SBC section to SBC-LTT section. The system does not allow this, neither at booking time, nor at charting time. If some one has to overcome this issue, he needs to book 2 tickets, one upto SBC and other from SBC, to be eligible for these quotas.

For RLGN, since it shares a part of the originating station, confirmed berths are given from the General Quota and sometimes from the Pooled Quota(Kindly go through the explanation of Pooled Quota)
Pass 1 (Confirmed, GN)
Pass 2 (Confirrmed, GN)
Pass 3 (Confirmed, PQ)
Pass 4 (WL 1, RLGN)
To end the discussion, kindly note Remote Quotas are not actually quotas but are Waitlist.
Confirmed berths for all of the Remote Quotas are given from the General Quota and sometime from Pooled Quota as explained in the earlier posts. Cancellation of the Remote Quota Waitlist's happens very slow. Hence it is always advisable to be placed against GNWL.
