Earth Day is an opportunity for SEPTA to reflect on the meaningful progress made to reduce environmental impact and operate more efficiently. Many of these improvements are visible to riders, including upgraded infrastructure, modernized facilities, and cleaner, more advanced fleet technologies. Other efforts happen behind the scenes, strengthening daily operations and supporting long‑term performance.
The project summaries below highlight systemwide efforts that enhance reliability build long term resilience and support responsible resource use. Together they show how sustainability is helping guide the way SEPTA plans invests and delivers service across the region.
Wissahickon Transit Center (opened December 2025)
The Wissahickon Transit Center is one of SEPTA’s most significant green infrastructure investments to date. It transforms a previously 100 percent impervious 3.3 acre site into a climate resilient stormwater managing and environmentally restorative transit hub. The project includes a 0.8 acre green roof and five rain gardens covering 0.26 acres that together divert an estimated 1.8 million gallons of stormwater each year from the Schuylkill River watershed.
These features reduce runoff pollution limit flooding cool heat prone areas and support native pollinators and wildlife. New vegetation lowers surface temperatures improves the operator facility’s energy performance and provides shaded resilient public space for riders. By replacing pavement with greened acreage and applying best practice BMPs the WTC improves environmental quality in Northwest Philadelphia and supports SEPTA’s goals for stormwater reduction climate adaptation ecosystem health and equitable access to green space.

Ballast Car Solar Retrofit
SEPTA’s Ballast Car Solar Retrofit Project converts two formerly scrap bound ballast cars into solar powered remote controlled units eliminating the need for rotary dump truck deliveries. Each retrofitted car replaces ten diesel dump trucks avoiding 4708 gallons of fuel each year and substantially reducing emissions and neighborhood truck traffic. The project diverts eighty tons of metal from the waste stream integrates dual 100 watt solar panels for zero emission gate operation and improves worker safety by removing staff from hazardous manual dumping. These efficiencies reduce pollution protect track adjacent environmental justice communities from diesel exposure and noise and support SEPTA’s broader climate circularity and resiliency goals.

Wyoming Complex Stormwater Retrofit Project
The Wyoming Complex Stormwater Retrofit includes ten rain gardens three subsurface detention basins and five oil and grit separators that together manage and treat stormwater from nearly fifteen acres of the site. These improvements replace aging drainage infrastructure while expanding landscaped and vegetated areas reducing impervious surfaces capturing and filtering runoff and improving overall water quality and infiltration.

Midvale Green Shield & Fencing Project
The Midvale Green Shield & Fencing Project improves environmental conditions around the Midvale Bus Depot by installing a green buffer including native low maintenance vegetation along Roberts and Wissahickon Avenues. Plantings include seventy eight trees thirty two shrubs more than one thousand perennials plants and grasses and native seed mix across nearly half an acre. These features enhance canopy cover air quality soil stability and visual screening of depot operations.
Improvements also include estate fencing regrading and pervious planting areas that reduce stormwater runoff and improve infiltration. By preserving existing walls sidewalks and trees where possible the project avoids unnecessary demolition and reflects a lower carbon approach.
Together these upgrades create a resilient green shield that strengthens stormwater management reduces operational impacts improves neighborhood aesthetics and supports SEPTA’s broader sustainability and community quality of life goals.

Elk Hill Solar Project (Elk Hill 1 & 2 Solar Farms)
SEPTA’s off site solar farm Elk Hill located in Franklin County Pennsylvania delivers forty two megawatts of renewable energy while generating meaningful revenue for the Authority. Producing up to sixty four gigawatt hours of electricity each year Elk Hill offsets approximately sixteen percent of SEPTA’s total electricity needs. Because SEPTA’s trains subways and trolleys operate entirely on electricity this clean energy directly supports more sustainable lower emission commutes for riders.
Since coming online in twenty twenty one Elk Hill has generated more than one million dollars in net revenue reinforcing the project’s value as both an environmental and financial asset. Sustainability extends beyond energy production as the site is planted with pollinator friendly seed mixes including native wildflowers and clover. In partnership with Lightsource bp SEPTA supports environmentally responsible land management by working with a local farmer who uses sheep grazing to maintain vegetation beneath and around the solar panels.

125 Buses with Integrated Stroller Spot (launched May 2025)
A dedicated stroller zone was added to one hundred twenty five buses to make boarding safer smoother and more convenient for families. The space is fully separate from ADA seating which preserves accessibility while offering dependable accommodation for riders traveling with young children. This improvement increases safety accessibility and overall customer experience and encourages more families to choose transit instead of driving. It also supports more equitable multimodal mobility which is a key strategy for reducing car dependency and related emissions. By optimizing interior space without increasing a vehicle’s environmental footprint the project improves operational efficiency while advancing SEPTA’s sustainability goals.

Hydrogen Fuel Cell Electric Bus Pilot (Launched Summer 2025)
SEPTA is testing 10 hydrogen fuel cell buses as part of its transition to a zero emission fleet. These buses produce only water vapor at the tailpipe and provide a cleaner alternative to diesel vehicles. The pilot program generates critical data on performance and infrastructure requirements and helps SEPTA identify the optimal balance of hydrogen and battery electric technologies to reduce greenhouse gas emissions across the system.

SEPTA’s Earth Day Celebration is happening on April 22 from 11AM to 2PM at 1234 Market Street and everyone’s invited! Stop by for fun interactive displays and a chance to see how we’re moving sustainability forward.
We’re energized by the work underway to position SEPTA as a best‑in‑class leader in sustainable transit and long‑term system stewardship. Thank you for championing these efforts and helping us keep raising the bar for what a modern forward‑thinking transit system can deliver.
