The Trolleybuses of
M É R I D A
Cities with complex geography – mountains, valleys, steep grades, rivers, airports in the center of town – have special traffic problems. The city of Mérida and Alberto Carnevali Airport straddle a long, narrow plateau between two river valleys high in the Andes Mountains [NASA]:
The airport runway in the center of this satellite view is 1,373 m long and lies at altitude 1,526 m. Only two streets go around it. Private homes, shops and other structures crowd the edge of the precipice that drops 150 m toward the Chama River on the right. [See airplane view.] The Teleférico de Mérida, the world's longest and highest aerial cableway and the principal tourist attraction in Venezuela, climbs from a point nearby to Pico Espejo at 4,765 m. Pico Bolívar next to it, at 4,981 m, is the highest mountain in Venezuela. Mérida's population today is about 400,000. It may be the smallest city in the world with a mass transport system.
Mérida was never connected with the rest of Venezuela by railroad and never had a tramway of any kind. Urban and interurban transportation were always provided by gas- or diesel-powered buses. When traffic along the plateau reached the saturation point in the 1970s, the local government created the Oficina de Transporte to try to solve the city's transport problems. In 1976 the Oficina proposed an aerómetro, an elevated railway, from Mérida to Ejido, a suburban town 11 km southwest [see map]. It was not built. In 1983 engineers at Universidad de Los Andes proposed a ferrocarril magnético called "Telmagv" across the city. Nothing came of that plan. In 1996 the administration formed the Oficina Metropolitana de Transporte Masivo (OFIMETRO) which acquired $60 million from the federal government for the construction of a 13 km monorriel along the south bank of the Albarregas River. That plan also collapsed. Finally, in 1998, Ofimetro proposed a reserved-lane trolleybus system modeled on the very successful line that had opened in 1995 in Quito, Ecuador. Ofimetro wanted two trolleybus lines on either side of the Albarregas River and a funicular railway down the escarpment to San Jacinto in the valley. For its main lines, the trolebús was the technology that was chosen and is still being implemented in Mérida today. (See Ofimetro logo.)
A new agency called Transmérida, organized in 1999, secured a USD $108 million loan from the Spanish, French, German and Dutch governments for the construction of 45 articulated trolleybuses and the first trolleybus line, a 19 km route between Ejido and La Hechicera [see map]. A consortium of DYCVENSA and Grupo AM of Venezuela, Adtranz (DaimlerChrysler) of Germany, Mercedes-Benz España, the Spanish firm Dragados and Systra of France was organized to build the line. The contract for the construction of the 45 vehicles was awarded to the companies that had supplied 113 trolleybuses to Quito: Hispano Carrocera and Mercedes-Benz of Spain. Pininfarina of Italy designed the vehicle bodies, inside and out. Electrical equipment was originally supposed to be supplied by Kiepe Elektrik of Germany, but ultimately came from Bombardier of Canada. Here are photographs of the Mérida prototype vehicle (see paper model by Rodolfo Cammalleri). Note that it has doors on only one side and they are designed for high-level, platform loading. The trolleybus can operate electrically or by using an auxiliary diesel motor [Hispano Carrocera]:
Construction of Mérida trolleybus line #1 began in February 2000 and was immediately beset with problems. The Ofimetro project was rejected, then supported, then rejected again by the federal government. Financing was erratic and work was interrupted for long periods. Motorists complained of disruptions along the Av. Centenario - Av. Andrés Bello corridor, the only direct route between Ejido and Mérida [see map]. They became angrier still when its traffic lanes were rebuilt as reserved lanes for trolleybuses. The trolleybus company was reorganized and renamed Trolmérida, but progress remained slow. Both Ofimetro and Trolmérida posted webpages on the Internet, but none was kept current or did much to establish good relations with future passengers.
Construction of the vehicles, however, kept on schedule and Hispano Carrocera delivered 45 trolleybuses to Mérida between May and July of 2003. The photographs below show the Trolmérida shops in Ejido [see map]. The posts and overhead wire visible in the first view are part of a vía de prueba (test track) around the yard. There is no wire connection between the yard and the trolleybus line. The vehicles use their diesel motors to reach Terminal Ejido. Engineer Arturo Rivas scaled a 25 m light tower to get the first picture . . . [Arturo Rivas, Trolmérida]:
The government restored its support and finally, in 2005, after over five years of construction, Trolmérida completed the first 6.5 km of its trolleybus line between Ejido and Mérida [see map]. Except at level crossings the route is entirely in vías exclusivas, and since the stations are between the trolleybus lanes and the vehicles have doors on only the right side, they run left-hand, English-style, against other traffic. This photograph was taken from a station on Av. Andrés Bello [Jorge Paparoni]:

During the Juegos Andes (Andean Games) in December 2005, ten trolleybuses provided free rides for passengers between Ejido and the Estadio Metropolitano near Pan de Azúcar station [see map]. They used their diesel motors since installation of the overhead wire had not yet been completed. A year later, starting Sunday 26 November 2006 and continuing every Sunday thereafter, trolleybuses carried passengers between Ejido, Centenario, La Mara and Alto Chama stations. This time, except for reversals at both ends, operation was completely electric. Rides were still free. Finally, on 18 June 2007, Merideños celebrated the formal inauguration of the first section of their new trolleybus line, between Terminal Ejido and Pie del Llano station in Mérida, a distance of about 11 km [Gerardo Sánchez]:
Terminal Ejido was designed by Venezuelan architect Roberto Ameneiro, who also designed Alto Chama station [see below] and six stations of the metro in Valencia, Venezuela. The view is north [see map]. The trolleybus line follows Av. Centenario on the right. "Guaky", the red macaw on the pillar, was the mascot of Copa América 2007, the fútbol (soccer) tournament that began the following week in stadiums throughout Venezuela. The two photographs below show the trolleybus inauguration [Trolmérida website]:
This second picture was copied (with permission) from a 360° panoramic view taken that famous day by Gerardo Sánchez:

The photograph below shows Terminal Ejido during the Christmas holidays, 2007. The view is northwest [see map and diagram below]. The trolleybus on the right has deposited its passengers in the terminal. Passengers in the distance are clearing turnstiles (rides were still free) to board the trolleybus partly visible on the left. Trolmérida has offices and a control tower overhead. The stairway on the left leads to a pedestrian bridge over Av. Centenario [Gerardo Sánchez]:

The trolleybus in the picture below has its poles down and has either just arrived at Terminal Ejido or is preparing to leave there, using its diesel motor, for the garage [see map]. Note the Hispano, Mercedes and Bombardier logos below the window. The apparatus on the wires in the distance helps the trolleybus reattach its poles [Gerardo Sánchez]:

A busy scene in September 2008 [from the "Noticias" section of the Trolmérida website]:
Helicopter view of Av. Andrés Bello near La Parroquia station [see map]. Note left-hand operation [Alonso Moreno]:
The photograph below was taken in July 2007 during the Copa América fútbol competition. The view is west over Río Albarregas, at the point where it separates Av. Andrés Bello (lower left) from Av. Monseñor Chacón [see map]. Near the center of the picture two trolleybuses sit on either side of Pan de Azúcar station, and two more approach from afar. That's Ejido on the horizon and the Estadio Metropolitano atop the hill on the left. It is unclear whether the fútbol fans have just arrived, or plan to leave, by trolebús . . . [Alonso Moreno]:

Trolmérida struggled to extend the trolleybus line from Pie del Llano station closer to the center of town. Until it arrived there the company could not charge fares. Stations were not yet been outfitted for fare collection and passengers still rode free in 2009.
The original 1998 plan was to run the line down Av. Urdaneta to Plaza Glorias Patrias [see map]. But a 1999 revision moved the route to Av. 16 de Septiembre and created new problems: how to steer two contraflow trolleybus lanes through the bottleneck at Calle 53, already choked with traffic from Viaducto Sucre, and down Av. 16 de Septiembre, the busy east-west thoroughfare alongside the airport.Trolmérida solved the first problem by demolishing private homes and other structures west of Calle 53 and plowing a trolleybus path, behind houses, between Av. Andrés Bello and Av. 16 de Septiembre. The city added two automobile lanes – eastbound only – on the side. The action pleased motorists, but not residents who had been dislocated and there were angry demonstrations and numerous construction delays. The photograph below shows Pie del Llano station at the west end of the bypass – which at present is the eastern terminus of trolleybus service. The camera is facing east. Those are the automobile lanes on the right. That's Av. Andrés Bello extreme left [firstname.lastname@example.org]:
The next picture shows the bypass from the other direction. Pie del Llano station is in the distance. Av. 16 de Septiembre is behind the photographer [see map]. The automobile lanes on the left are for eastbound traffic only (westbound traffic uses Calle 53) [email@example.com]:
Looking east on Av. 16 de Septiembre, with the airport in the background [see map]. This was formerly a 5-lane road, with curb parking and two traffic lanes in each direction. The trolleybus reservation now occupies two lanes and there is room only for automobiles traveling east (westbound automobiles must use other streets). [firstname.lastname@example.org]:
This is María Mazzarello station [see map]. Part of the airport terminal, on the other side of the airport, is visible extreme left [email@example.com]:
Residents found the sign below: "Pardon the disturbances" / "We are working for you" [Gerardo Sánchez]:
On 4 August 2009 the name of the operator was changed from Trolmérida to Tromerca (Trolebús Mérida C.A.). Construction advanced on Line 3, a teleférico [aerial cableway] from Domingo Peña trolleybus station (formerly called Los Conquistadores) down to San Jacinto in the Chama River valley [see map]. The route was originally planned as a funicular railway. Twenty telecabinas arrived from the Austrian firm Doppelmayr Garaventa on 26 August 2011.
Trolleybus Line 1 was still far away, so Tromerca built a temporary terminal, an un-wired loop, near Mercado Periférico, a market complex at the east end of the airport. Trolleybuses started carrying passengers along Av. 16 de Septiembre to Mercado Periférico on 22 September 2012. They lowered their poles before entering the loop. The trolleybus line was now 13.1 km long – even though this short final section was not operated electrically [see map].
Two months later, on 26 November 2012, Tromerca announced that it had purchased 20 new diesel buses from Yutong in China to supplement the electric buses on its trolleybus line. On 15 December it inaugurated Line 3, the aerial cableway from Domingo Peña to San Jacinto [ESPASAMERIDA]:
Construction of the final segment of Line 1, a clockwise loop along Av. Tulio Febres Cordero and around the university campus to Domingo Peña terminus, began on 19 May 2014 [see map]. On 22 December 2014 – for the first time in its seven year history – the trolleybus company started charging fares.
Construction of the system had always been slow – beset with countless mechanical, financial and political problems. Completion of the first 11 km, from Ejido to Pie del Llano, took seven years [see map]. Construction of the next 2 km, to Mercado Periférico, took another five years. The company was embarrassed and residents were exasperated. For whatever reason, and without previous announcement, Tromerca staged a farcical "inauguration" of the final 2.1 km section, between Mercado Periférico and Domingo Peña stations, on Saturday 29 August 2015. The route still had no overhead wire and three of the four stations were not yet completed, so the trolleybuses continued to lower their poles at the airport and operate with their auxiliary diesel motors [Tromerca]:
It was not the real thing. But it provided some satisfaction to the public, who could now, for the first time, travel without changing from Ejido to Domingo Peña. The photograph below, taken on Sunday 22 September 2015 at the corner of Calle 38 and Av. Tulio Febres Cordero [see map], shows Luis Ghersi Govea station and the trolleybus wire which may be in service soon. It is hoped that this page will soon have pictures of vehicles using it...
