Tonka bean oil Tonka bean oil Tonka bean oil is extracted from the seed of "Dipteryx odorata". The oil is composed primarily of coumarin, which is used to flavor tobacco. It is neither a pressed oil, nor an essential oil, but was traditionally obtained by soaking the large, single tonka bean seed in rum or other alcohol for 24 hours, after which crystals of coumarin appear on the outside of the seed, and are then collected. The seeds contain up to 46% oil by dry weight. In recent years, most commercially produced coumarin are synthetic, which has reduced the demand for tonka beans
Renfe Feve However, from 1978 onwards, with the introduction of regional devolution under the new Spanish constitution, FEVE also began transferring responsibility for a number of its operations to the new regional governments. This happened in Catalonia (FGC) in 1979, in a portion of the Basque (Euskotren) network in 1982, in the Valencian Community (FGV) in 1986, and with the Majorcan Railways (SFM) in 1994.

The above-mentioned EFE (Explotación de Ferrocarriles por el Estado) also operated the Carabanchel – Chamartín de la Rosa
