A taller, upgraded version of the 3000 series, it was used from 1963 until 1999. The 3100 series was the longest Romancecar in common service and gave it its distinctive look. The Nagoya Railroad Panorama Car design was based on the 3100 series. The 11-car trainset could seat 464 people, and had a maximum design speed of 170 km/h. Odakyu 7000 series LSE: Entering service in 1980, it has a 180-degree front view of scenery. It has seating for 464 people in 11 cars—identical to the 3100 series. It was manufactured by Kawasaki Heavy Industries. The two remaining sets were withdrawn from regular service on July 10, 2018, and are scheduled to be operating seasonally until the end of the fiscal year. Odakyu 10000 series HiSE: Introduced in 1988, like its predecessor, the 7000 series LSE, these two types are very closely related, and were once the top grade of Romancecar service, but with larger seats than the 7000. Like the LSE and VSE, the driver's compartment is elevated so that passengers at the front of the train have an unimpeded 180 degree view of the scenery. These trains are used for Hakone services, plying the same route as the VSE but stopping more often; the trip to Hakone takes about 90 minutes. Cabin attendants are available for food and drink service, except in the evening. The two remaining sets were withdrawn on March 16, 2012. Odakyu 20000 series RSE: Introduced in 1992, and withdrawn in 2012, these trainsets were mainly used for Asagiri services to , where they alternated with the very similar JR Central 371 series. They were the only Odakyu trains with first-class seating in "semi-compartments" on the upper deck of two bi-level cars in the center of each train. It was the first in the series to break from the traditional wine red color, being baby blue. Odakyu 30000 series EXE: Introduced in 1996, these currently operate most Romancecar services. Most are equipped with vending machines on board, and some also have cabin attendants. They are boxy and metallic bronze in color. From fiscal 2016, sets have undergone a programme of refurbishment; refurbished sets are branded EXEα (Excellent Express Alpha). Odakyu 50000 series VSE: Introduced in 2005, the white VSE features the driver's compartment elevated over the cabin as with the HiSE. VSE trains are primarily used for Super Hakone services and have cabin attendants who
