The group's second LP, Queen II, was released in 1974, and features rock photographer Mick Rock's iconic image of the band on the cover. This image would be used as the basis for the 1975 "Bohemian Rhapsody" music video production. The album reached number five on the British album chart and became the first Queen album to chart in the UK. The Freddie Mercury-written lead single "Seven Seas of Rhye" reached number ten in the UK, giving the band their first hit. The album is the first real testament to the band's distinctive layered sound, and features long complex instrumental passages, fantasy-themed lyrics, and musical virtuosity. Aside from its only single, the album also included the song "The March of the Black Queen", a six-minute epic which lacks a chorus. The Daily Vault described the number as "menacing". Critical reaction was mixed; the Winnipeg Free Press, while praising the band's debut album, described Queen II as a "over-produced monstrosity". Allmusic has described the album as a favourite among the band's hardcore fans, and it is the first of three Queen albums to feature in the book 1001 Albums You Must Hear Before You Die.
What was the name of Queen's second LP?
A: Queen II

Network effects are a large factor with electrification. When converting lines to electric, the connections with other lines must be considered. Some electrifications have subsequently been removed because of the through traffic to non-electrified lines. If through traffic is to have any benefit, time consuming engine switches must occur to make such connections or expensive dual mode engines must be used. This is mostly an issue for long distance trips, but many lines come to be dominated by through traffic from long-haul freight trains (usually running coal, ore, or containers to or from ports). In theory, these trains could enjoy dramatic savings through electrification, but it can be too costly to extend electrification to isolated areas, and unless an entire network is electrified, companies often find that they need to continue use of diesel trains even if sections are electrified. The increasing demand for container traffic which is more efficient when utilizing the double-stack car also has network effect issues with existing electrifications due to insufficient clearance of overhead electrical lines for these trains, but electrification can be built or modified to have sufficient clearance, at additional cost.
What can be a drawback of electrification of long distance freight trains?
A:
electrification to isolated areas
