Hi Mr Cecil,
I've attached pictures of my office.

1. The exterior of my office building is oval shape, facing a railway track & an overhead bridge (I'm staying on the 17th floor overlooking it).
   
2. I've removed one of 2 toilets which was build side by side previously, with the drainage pipes still protruding from the ground though the pipes are tightly capped?? What is left is a the other toilet. this side of the wall ison the other half of my office. Please advice.
   Please refer to photos below.
   

In my opinion, if your office is on the 17th storey, the external building (and it's spine) and the mrt tracks are not considered a poison arrow or a sha qi.
In fact, if there is really a threat, it could be the lamp post as shown in the attachment - especially for lower floors. Since you are at 17th storey, it is impossible for this lamp post to be a poison arrow.
Concentrate on improving the Feng Shui of the interior of the office, instead.
