I know their are the 8 depots that use numbers 1-7 and 9 to tell what depot that bus is from. But what do the other numbers mean? I still can't tell the difference. Can someone explain to me the block numbers? |

SEPTA uses a four digit block system which identifies each run scheduled. That number doesn't change if a operator does multiple routes in one shift. 1-Comly 2-Frankford 3-Midvale 4-Victory Avenue/Red Arrow Lines 5-Allegheny 6-Frontier 7-Southern 8-Elmwood LRO 9-Callowhill For more information look here. |

It happens..... oh, and while the Suburban "K"'s have a 3 digit holder and the city "K" cars have two, they still have a 4 digit block and must identify as such. LRO Blocking (Callowhill IDs in parentheses) 10-805x (905x) 11-810x 13-815x 15-800x (900x) 34-820x 36-825x 51-870x (Yes the 51 - Welcome Line is still technically in the books.) |

The reason (as I was told) why the blocks for the buses do not change even if a driver operates multiple routes that do not share blocks is due to a glitch in the Orbital system. When it first came out, the blocks changed with each non-cross routing route the driver may have gone to. And to add....the Market-Frankford and Broad Street lines use the 4-digit block system as well. There are no block displays on the M-4's and the B-4's display the last 2 digits of the block. MFL Blocks - xx51-xx99 BSL Blocks - xx01-xx20 (locals), xx21-xx40 (expresses), xx41-xx50 (Ridge), and xx91-xx99 (blue light specials). I need to look up the prefixes for those two lines later today when I'm downtown. |

Hi, I know that this is an older post, but I found this and I do know a thing or two about block numbers. The BSL and MFL actually DO only have two-digit block numbers. But there are two major differences regarding how BSL and MFL blocks work. Since the BSL consists of a wider variety of service types (local, express, ridge, stadium specials), the block numbers are more frequent, and therefore, operators don't operate with the same block all day. MFL is different. Since it is only two tracks and consists of pretty much all local trains, the blocks aren't as constant, so therefore operators on the MFL operate under the same block/run number all day. |

There is an operator on the El , that always says welcome to train 56. that's the last 2 digits of his block, I guess. |
