| 摘要 | A train control system (fig. 2) and method (fig. 3) use signal information from a next block to change a restrictive signal in a block currently occupied by a train to a less restrictive signal if it can be ascertained that the condition causing the more restrictive signal has changed. This may be accomplished by receiving signal information from the next block while still in the current block and, if the signal information from the next block is no more restrictive than the signal information in the current block, and the signal in the current block is of a type that can safely be modified, allowing the train to operate as if the signal information for the current block were less restrictive than the actual, previously received signal information for the current block. | ||||||
