Columns

The Blocking tab contains two grids: Blocked and Unblocked.

Both grids contain the same set of columns, except for the Lo (Layover) and Dhd (Deadhead) columns, which only appear in the Blocked grid.

You can adjust the width of the columns. If you display the supplementary data, you can also move the splitter between the grids and the supplementary data to adjust their width.

Table 1. Column Values
Header	Description
Frz (Freeze)	Indicates whether the trip is frozen or not.
DT	Deadhead types: Garage (Pull-in or Pull-out) and Interline deadheads when not using implied deadheads.
Block	The block number of the specified trip. Applies to blocked trips only although it also appears in the Unblocked trips grid. In manual blocking, you can manually hook trips in the Unblocked trips grid using this column, that is, type the block number to which you want to hook the trip.
BlockId	This is an additional block number identification and is typically used for custom reports. It also appears in the Unblocked trips grid. For custom block ID, you can use alphanumeric characters.
From (From node)	The abbreviated name of the start node of the trip.
Time (From time)	The time when the vehicle arrives at the start node of the trip.
Time (To time)	The time when the vehicle arrives at the end node of the trip.
To (To node)	The abbreviated name of the end node of the trip.
Lo (Layover/Recovery time)	Applies to blocked trips only. This refers to the time between one trip and the next trip.
Dhd (Deadhead time)	Applies to blocked trips only. For applicable trips, the deadhead time gets its information from the Deadheads tab.
Line	The line to which the trip belongs.
Pattern	The pattern of the line to which the trip belongs.
Serv (Service)	The service to which the trip belongs.
MinLO (Minimum Layover)	The value you type should be based on the policies and union agreements of your transit site. If you do not use any layovers, the default is set to NA (with a value of -3600 seconds or -1 hour).
MaxLO (Maximum Layover)	The value you type should be based on the policies and union agreements of your transit site. If you do not use any layovers, the default is NA (with a value of -3600 seconds or -1 hour).
Mileage	Shows the total trip distance. This should match the pattern distance.
Dead Mileage	Shows the total deadhead distance, that is, sum of interline and garage deadhead distances.

Note: Using the global value set as the default is recommended in the Minimum Layover and Maximum Layover fields. The values in these fields should be changed with caution as they affect possible trip linking solutions, that is, changing your layover on trips could result in the creation of blocks with one or two trips due to the inability of the system to find other trips to link together.
