SEPTA 2019 New Flyer XDE40 on Route K

On February 12, 2012, SEPTA eliminated route C in favor of routes 4 and 16. While many people protested this change, saying that the C bus has always been the C, this actually raises the following question: why? Why was the C bus ever route C? Why are there some SEPTA routes that are letters, and some that are numbers? What made SEPTA routes be letters in the first place? This article is here to answer your questions.

In the Beginning…

In 1902, when Philadelphia Rapid Transit Company, or PRTC, came to exist, all lines were either rail lines. That means not a single diesel bus operated on the streets of Philadelphia.

And Then The Buses Came…

It wasn’t until the 1920s, where buses began to come into operations, but at first, these buses were all powered by electricity. See, in 1923, PRTC began operating what is now known as “trackless trolleys” on a route numbered 80, which operated along Oregon Avenue. Around this same time, traditional buses started to join the ranks on new routes that operated where a trolley could not (due to being proven by the trackless trolleys, that it’s more convenient to move service without also having to move tracks). These new bus routes would receive letters, to make it clear that these routes would not use electric vehicles.

On Came The Double-Letters

Over time, so many new bus routes were created, that all letters A through X ended up being used, so PRTC would begin making route X1, XA-XO. The X simply meant that it continued from X but was still was its own route, not “express” as people would eventually believe as route XH runs a quicker route than the regular route H, despite ending and starting at the same locations.

The PTC Era – Buses Become Numbers

In 1940, Philadelphia Transit Company would begin operating transportation in the city of Philadelphia while taking over operations from PRTC as well as a few private operations. One of the first things PTC would do with the new leadership was to replace aging vehicles with new modern vehicles, which included buying new PCC cars. Ironically, shortly after this, most trolley routes were converted to bus routes. This trend became increasingly common, to the point that by 1960, PTC went from operating all routes 2 through 66 as a trolley or trackless trolley routes (although a few of these would be discontinued on their own right), to only having routes 6, 10, 11, 13, 15, 23, 29, 34, 36, 47, 50, 53, 56, 59, 60 and 66 as electric routes, while the remaining lines operated with traditional diesel buses. From this point forward, all new diesel bus routes would receive numbers instead of letters.

The SEPTA Era: Letters replaced by Numbers

By the time SEPTA took over operations of the Philadelphia transit service in 1968, there was already a mix of lettered and numbered bus routes. At this point, most old routes would retain their former designators in the city with a few changes here and there in the early 70s. It wasn’t until the 1980s that SEPTA would begin massively changing route designators. The goal was to have all letter routes as numbers by the 90s, however around 1993 SEPTA was under new management, and a lot of that particular plan was put on the back burner in favor of new technology (aka talking buses, and the then-new M4 cars). In 1995, SEPTA would drop a few more letters in favor of numbers, including route X which became route 77, and route E which became route 65. However, it wouldn’t be until 2012 that SEPTA would again replace a letter route with a number. This is when the C would be split into routes 4 and 16. There’s no clear future on the letter routes, but as it stands now the letters are simply a relic of times past.

If you read this, congratulations, you have been educated. Below is a list of SEPTA’s letter routes and what numbers they became. This chart also lists the year each letter would last be used.

About the author: Dash Verified icon 1

I have been with Virtual Transit Center since it's conception as the "Dash Forums" back in 2008. Since then, I have been writing and doing YouTube side by side, focusing both on Transportation and Gaming. Most of my knowledge comes from SEPTA as I lived in Philadelphia for most of my life. As of 2021, I am on YouTube as DashTransit, Dash5155, and TheDashOfficial.

As for the name DashTransit itself, it actually stems from my YouTube channel.

DashTransit was originally called "njt5329" and the channel was just clips of buses. Mostly SEPTA and NJT. A Fujifilm Finepix was used in this era.

Starting in July 2011, the Canon SX130IS camera became the camera of the channel, bringing HD documentary-style videos much like my buddy (trainman1971) did for DVD for many years past. This is when the channel became known as "Transit Action Series"

In May 2012, the original Canon SX130IS retired, and then all videos were recorded off a mobile phone until eventually uploaded proved too difficult due to hardships IRL

Starting in 2017, I used a Canon SX200IS from Bastranz to reboot the channel that otherwise was dead for a whole year prior.

Between April 19th, 2019, and January 21st, 2021, all videos were recorded by a Canon SX710 HS camera. The channel was renamed DashTransit 4/19/19.
