Monrovia station is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Monrovia station rather than just read about it. In short: Monrovia station is an at-grade light rail station on the A Line of the Los Angeles Metro Rail system. It is located at the intersection of Duarte Road and Myrtle Avenue in Monrovia, California, after which the station is named.

Key takeaways

Monrovia station belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Monrovia station to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Monrovia station from memory before moving on to harder problems.

Reference excerpt

Monrovia station is an at-grade light rail station on the A Line of the Los Angeles Metro Rail system. It is located at the intersection of Duarte Road and Myrtle Avenue in Monrovia, California, after which the station is named. This station opened on March 5, 2016, as part of Phase 2A of the Gold Line Foothill Extension Project.

History The Los Angeles and San Gabriel Valley Railroad built the first train tracks and station in Monrovia in 1887. The Los Angeles and San Gabriel Valley Railroad was founded in 1883, by James F. Crank with the goal of bringing a rail line to San Gabriel Valley from downtown Los Angeles. Los Angeles and San Gabriel Valley Railroad was sold on May 20, 1887 into the California Central Railway. In 1889 this was consolidated into Southern California Railway Company. On January 17, 1906 Southern California Railway was sold to the Atchison, Topeka and Santa Fe Railway and designated the Pasadena Subdivision. Installed in 1887, a mule-drawn railway with a single passenger car, called the Myrtle Avenue Railroad at that time ran from the Monrovia station up Myrtle Ave to downtown Monrovia. On the way back down to the rail station, the mule was loaded onto a flatcar and downhill gravity took the cars back to the station. By the early 1920s the partially mule-powered streetcar system was removed. In 1906 the first Pacific Electric rail car arrived in Monrovia. The PE Pasadena and Monrovia line ended in 1951. Santa Fe Middle School near the station is named after the Santa Fe Railway.

The current railway station reuses the former Atchison, Topeka and Santa Fe Railway depot which was built in 1926. It is designed in a Spanish colonial revival style. The 1926 station replaced a wooden depot built on the site in 1886 by the original Los Angeles and San Gabriel Valley Railroad. Passenger trains ceased to stop at Monrovia by April 1956, though the station's passenger ticketing office remained open through the late 1960s. Santa Fe and later Amtrak ran the Southwest Chief and Desert Wind over this line in Monrovia, but rerouted passenger trains to the Fullerton Line in 1986. The Santa Fe line served the San Gabriel Valley until 1994, when the 1994 Northridge earthquake weakened the bridge in Arcadia. With the completion of the Gold Line in Monrovia, the 1926-era Monrovia train station is slated to be restored. The Santa Fe Depot was used in a number of Hollywood movies through the years. It is used two times in the 1966 movie The Trouble with Angels, both at the start and the ending in which the girls leave St. Francis Academy.

Vehicle maintenance facility As part of the light rail extension, the Gold Line Authority and Metro built a new Maintenance and Operations (M&O) Facility in Monrovia, east of Monrovia station. The 27-acre (11 ha) facility services, cleans and stores light rail vehicles for Metro's fleet, with a total storage capacity of 104 vehicles. The facility, known as Metro Division 24 Yard, is located just north of the right of way between California Avenue and Shamrock Avenue. It cost $53 million to build.

Service

Hours and frequency A Line service hours are from approximately 4:30 a.m. and 11:45 p.m. daily. Trains operate every 8 minutes during peak hours, Monday to Friday. Trains run every 10 minutes, during midday on weekdays and weekends, from 9:00 a.m. to 7:00 p.m. Night and early morning service is approximately every 20 minutes every day.

Connections As of September 19, 2025, the following connections are available:

Foothill Transit: 270

Neighborhood and destinations The city of Monrovia created a transit-oriented district around the station. The district, known as the Station Square Transit Village Mixed Use District, has mixed retail, residential and office uses, with pedestrian amenities and connections. Construction of phase one of the new district started in 2017. Between the station and the I-210 Foothill Freeway is the Station Square Transit Center, with a park and parking lot, also new apartment buildings. Plans are to restore/renovate the historic 1926 Monrovia Santa Fe train station depot at the location, though the actual use of the station is not yet determined as of 2013.

Worked examples

Example 1 — a first encounter with Monrovia station

Start with the simplest possible case. Write down what Monrovia station claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Monrovia station before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Monrovia station ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Monrovia station

In research: Monrovia station appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Monrovia station in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Monrovia station is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1926 establishments in California, 1972 disestablishments in California, 2016 establishments in California, so understanding it makes those chapters shorter.
In everyday life: Look for Monrovia station outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
