asakusa line express train to haneda airport

I notice there is an express train from city to haneda airport without transfer at sengakuji station.
However I can't find any information about the timetable of this train. Could someone please help me with the link.
Can I take this train from any asakusa line station?
thank you

Try to use Route/Fare search here:

In Japanese, here is the timetable for Sengakuji. There are three tables; 平日/Weekdays, 土曜/Saturdays, and 休日/Others

羽 for Haneda Airport. Colors are train types here:
http://www.keikyu.co.jp/train-info/kakueki/

Yellow/Airport Kaitoku/エアポート快特 only stops at Shinagwa.
Green/Kaitoku/快特 plus Keikyu Kamata.
Red/Tokkyu/特急 and Blue/Airport Kyuko/エアポート急行 some more.

Anyway, there are so many trains to Haneda; up to 6 trains per hour. I do not care about types of the trains in this case.

I also cannot find a timetable here http://www.haneda-tokyo-access.com/en/.

However, what time will you exactly arrive? I see in Hyperdia that there are continuous trains (2 arrow down icon at Sengakuji; only changing names from Keikyu to Toei Subway) that will take you from Haneda International Terminal to Asakusa.

Trains arrive at Haneda roughly each ten minutes, so the timing is not usually a problem.

A similar question was asked recently about the transfers and the short answer was they are very easy (across platform style).

it's clear now.. thank you all

Similar Q timetale is NOT Asakusa line "Asakusa/浅草(A-18)".
It was Asakusa line "Asakusabashi/浅草橋(A-16)" stn.
https://en.wikipedia.org/wiki/Toei_Asakusa_Line
A-16,A-18 are "stn number(ing)" for Tokyo beginners.

All Toei Asakusa line/Keikyu trains are no need option fee plus also no reserved seat car with.
All trains are regular "commuter type" with straps for standing passengers.
Asakusa line wiki mentioned 5 companies cars using as "thru service".

Any company trains are same fare no worry. (PASMO/Suica covered)
But if using discount Subway Pass no covered after Sengakuji.
Keikyu is NOT Subway companies(Toei and Tokyo Metro) in Tokyo.

Hyperdia seems to be quite famous in the English speaking society, however, Jorudan is much popular in Japan. Jorudan has already been incorporated in Google Maps. Moreover, their newly refurbished English standalone version has started to operate. Jorudan's [Low] (price), [Easy] (transfer), and [Fast] (arrival) icons are very useful.

In this particular route to Haneda, Keikyu's planner add some more options, such as "time needed for transfer".
