In March 2014, a contract was signed for the acquisition of ten secondhand trolleybuses from Verkehrsbetriebe Luzern, the operator of the Lucerne trolleybus system, in Switzerland, by Trolebuses de Chile SA (TCSA),  operator of the Valparaíso trolleybus system since 2007 (see below).
The vehicles concerned were built in 1989 by NAW, but were still younger than every vehicle in the TCSA fleet but one (a 1991 Shenfeng unit), and much younger than most, as the next-youngest vehicle in the fleet at that time was built in 1966.
 They are 12-meter, two-axle trolleybuses and were the first trolleybuses acquired by the system since 1992.
The first vehicle arrived in Valparaíso on 28 June, followed by the other nine between September 2014 and January 2015.

The start of testing of the vehicles was delayed several months after it was discovered that current traffic regulations prohibited transit vehicles as old as these from operating in passenger service, TCSA's existing fleet having been granted an exemption some years ago.
 The regulations were amended in early 2015, and testing and training with the ex-Lucerne NAW trolleybuses began in mid-February 2015.
They began to enter service on 23 March 2015, and all 10 had entered service by 1 April.
 TCSA later purchased another eight trolleybuses of the same type from Lucerne.
 Four arrived in August 2017 and entered service in October 2017, while the final group of four arrived at the end of November 2017 but had not yet entered service as of January 2019, more than a year later.
