1, CTC system: it is the technical equipment that the dispatching center centrally controls the signal equipment in a certain section and directly directs and manages the train operation.

2.TDCS system: It is a dispatching command and management system covering the whole railway, which can provide modern dispatching command and management means and platforms for railway dispatching command and management personnel at all levels in a timely and accurate manner.

Second, the characteristics are different.

1, CTC system: through centralized control, the automation degree of train dispatching is improved, and the safety and efficiency of railway transportation are ensured, thus making full use of line capacity, improving labor productivity and working conditions.

2.TDCS system: It is divided into three layers: Ministry center TDCS system, railway bureau TDCS system and station system. It adopts digital, networking and information technology, which is a revolutionary breakthrough to the traditional dispatching command mode, greatly reducing the labor intensity of dispatchers and improving the transportation production efficiency.

Third, the operation mode is different.

1, CTC system: It has the characteristics of high security, high reliability and intelligence. Different from the traditional dispatching mode, it uses advanced computer communication technology to complete the dispatching plan and command through the computer network. The station self-discipline machine conducts self-discipline according to the dispatching plan, and the corresponding peripheral devices collect all kinds of real-time information along the railway and transmit it to the central server of the dispatching center.

2.TDCS system: directly command the first floor of TDCS station system of railway administration. TDCS of railway administration realizes real-time, centralized and transparent command of the traffic of the whole railway administration, adjusts the transportation scheme by automatic means, and issues the traffic plan and dispatching command through computer network.

Realize the automatic reporting and tracking of train numbers, and change the backward way that station attendant manually reports points to the dispatcher by telephone, and the dispatcher issues plans and orders to the station by telephone, and the station manually copies points and repeats them.
