Can I connect through any service?

Heathrow Connect is a train service in London, connecting Heathrow Airport with Paddington station. It is a joint venture between First Great Western and BAA. The service follows the same route as the faster Heathrow Express service but serves intermediate stations on its route, thus connecting several locations in west London with each other, the airport, and central London. It normally leaves from Platform 11 at Paddington.
