What is "Automatic Ghat Section Working"?
Is this training for those working on the Braganza Ghat and Shiradi ghat of SWR?
Looks like a typo. Most probably, it is Absolute block working, Automatic signalling and Ghat section working. Due to the gradients, there are some restrictions in implementing Automatic signalling on ghat sections ( Implementation of the automatic signalling on the SBC-BNC section was delayed due to the gradient between the two stations), so the 'Automatic Ghat section working' may be a typo..
Both come under absolute block working.
In absolute block working, the route is divided into blocks and only one train is allowed in each block at any time. These blocks are controlled using signals or tokens. Signalling and token systems are just ways of implementing an Absolute block system.
Even the automatic signalling sections we see in IR are technically Absolute block systems. Its just that instead of manual signal control or token exchange, the trains and track circuits control the signals automatically.

The blocks are controlled using signals or tokens; but in signals more trains are operated even if a single line is there, with many trains looped at intermediate stations or intermediate loops for crossing with other trains.
But token means - no matter how many intermediate stations or loops are present, just one train is allowed and till that returns back to the starting point, no other trains are allowed. Right?
Like if a train is allowed from GIN then no other is allowed till it goes to CKBK and...
