Good morning and welcome to the Black Mesa Transit System. This automated train is provided for the security and convenience of the Black Mesa Research Facility personnel.

The time is 08:47 AM. Current topside temperature is 93 degrees, with an estimated high of one hundred and five. The Black Mesa compound is maintained at a pleasant 68 degrees at all times.

This train is inbound from Level 3 Dormitories to Sector C Test Labs and Control Facilities. If your intended destination is a high-security area beyond Sector C, you will need to return to the Central Transit Hub in Area 9 and board a high security train. If you have not yet submitted your identity to the retinal clearance system, you must report to Black Mesa Personnel for processing before you will be permitted into the high security branch of the transit system.

Due to the high toxicity of material routinely handled in the Black Mesa compound, no smoking, eating, or drinking are permitted within the Black Mesa Transit System.

Please keep your limbs inside the train at all times. Do not attempt to open the doors until the train has come to a complete halt at the station platform. In the event of an emergency, passengers are to remain seated and await further instruction. If it is necessary to exit the train, disabled personnel should be evacuated first. Please stay away from electrified rails, and proceed to an emergency station until assistance arrives.

A reminder that the Black Mesa Hazard Course decathlon will commence this evening at nineteen hundred hours in the Level 3 Facility. The semifinals for high-security personnel will be announced in a separate Secure Access transmission. Remember, more lives than your own may depend on your fitness.
