Train control method and system
DCFirst Claim
1. A train control system for controlling at least one train travelling in a track network comprising at least one track having at least one signal associated with a portion of the at least one track, the system comprising:
- an onboard track database comprising at least one of the following;
train data, track network data, track data, signal data;
a positioning system configured to determine position data directed to a position of the at least one train within the track network; and
an onboard control system configured to;
(i) receive position data from the positioning system and signal data from the track database; and
(ii) based upon at least one of the following;
train data, track network data, track data, position data, signal data, train control data, authorization data signal aspect data, or any combination thereof, predictively enforce the next, upcoming signal by automatically braking the at least one train prior to encountering the next, upcoming signal, unless;
(a) based at least partially on current signal aspect data, a determination is made that it is safe to proceed towards the next, upcoming signal;
(b) specified authorization data is received;
or (c) specified train control data is received.

Abstract
A train control system for controlling trains traveling in a track network including tracks with signals associated therewith. The system includes an on-board track database, a positioning system and an on-board control system. The on-board control system receives position data and automatically brakes the train prior to encountering an upcoming signal based upon specified data points. The train is not automatically braked if certain conditions are met. A method for controlling a train traveling in a track network is also disclosed.

23. A method for controlling at least one train travelling in a track network comprising at least one track having at least one signal associated with a portion of the at least one track, the method comprising:
-
determining at least one of the following;
train data, track network data, track data, signal data;determining position data directed to a position of the at least one train within the track network; and based upon at least one of the following;
train data, track network data, track data, position data, signal data, train control data, authorization data signal aspect data, or any combination thereof, predictively enforcing the next, upcoming signal with a train control system by automatically braking the at least one train prior to encountering the next, upcoming signal, unless;
(a) based at least partially on current signal aspect data, a determination is made that it is safe to proceed towards the next, upcoming signal;
(b) specified authorization data is received;
or (c) specified train control data is received.

24. A train control system for predictively enforcing a stop for at least one train travelling in a track network having at least one track with at least one signal associated with a portion of the at least one track, the system comprising an onboard control system configured to:
- (i) receive train position data and signal data;
(ii) display a prompt to an operator of the at least one train for specified authorization data to allow the at least one train to proceed without operational compliance of a next, upcoming signal, unless specified train control data indicating operational compliance of the at least one train for the next, upcoming signal is received prior to encountering the next, upcoming signal; and
(iii) based upon at least one of the following;
train data, track network data, track data, position data, signal data, train control data, authorization data signal aspect data, or any combination thereof, predictively enforce the next, upcoming signal by automatically braking the at least one train prior to encountering the next, upcoming signal, unless;
(a) based at least partially on current signal aspect data, a determination is made that it is safe to proceed towards the next, upcoming signal;
(b) the specified authorization data is received;
or (c) the specified train control data is received.
- (i) receive train position data and signal data;
