Introduction
The 12th International Workshop on Top Quark Physics (TOP 2019) will be held at Institute of High Energy Physics (IHEP), Beijing, China, from September 22nd to 27th. Following the long tradition of the workshop series, the 2019 edition will be dedicated to an overview of the most up-to-date experimental measurements at the Large Hadron Collider (LHC) and latest theoretical developments on top quark physics. Special focus on theoretical developments related to physics beyond the standard model will be given in a Mini-Workshop with the name “Top Meets New Physics” that will take place on Thursday, September 26th. There will also be a session on top quark physics at future facilities such as the High Luminosity LHC and CEPC/SppC. We are looking forward to meeting you in Beijing this coming September.

Transportation
Directions from Beijing Capital International Airport to IHEP:
1) By taxi:
You can get a taxi right outside the arrival terminals. Taxies wait there in line. The normal taxi driver will not soliciting business in person at the Airport arrival terminals hall. It is about 40 km from the airport to IHEP. It takes 50-60 minutes from the airport to the IHEP. The fare is about 150 RMB (~ 20 EUR) depending on time of day and traffic conditions. If you take the taxi, you may sow the following note A/B /C to the taxi driver.
2) By subway:
You can take Beijing Subway Airport Express from Airport Terminals 2 and 3 to Dongzhimen Station, from which you should transfer to Line 2. Change from Line 2 to Line 1 at Jianguomen Station, taking the train in the Pingguoyuan direction, and get off at Yuquanlu Station, exiting by the north-west exit (A). The IHEP campus is just at the north-west corner of the crossroads; you can enter by the south gate (300 m west of Subway exit A). Note that the subway may be extremely crowded at peak times and that you will have to negotiate long flights of stairs, so it is unsuitable if you have heavy baggage or mobility problems. 12
3) By Airport shuttle bus:
There are numerous airport shuttle buses to different parts of the city. The closest to IHEP is route 16 towards Shijingshan, getting off at Lugu (third last stop). From there, you can take a taxi to IHEP for about 13 RMB (~1.7 EUR). You can also take bus route 4 to Gongzhufen, getting off at the last stop. From there you can take a taxi to IHEP for about 25 RMB (~3.2 EUR). The shuttle bus fare is about 30 RMB (3.8 EUR). If you take the Taxi, you may sow the following note A/B /C to the taxi driver.
If you take taxi, please show this to the taxi driver
