WHEN a passenger on a train, it can be difficult to report crimes in the open.

Being in a confined space, not everyone can easily call the emergency services without drawing the attention of people posing a danger.

The British Transport Police (BTP) has measures in place for passengers to contact them discreetly.

Here is everything you need to know on how to contact the force when in a sticky situation on a train.

How to text the force

You can text on 61016 to tell BTP about non-emergency incidents. In an emergency always dial 999.

What information should I include in my text?

Tell them the nature of the incident, the location and the time. For example, ‘Abusive man on the 7pm Southend Victoria to London Liverpool Street service. He was threatening people, and then got off at Grays.’

Will I get a reply?

You will receive a text to confirm that your message was received. BTP will then follow up and ask for more information if required, or let you know what action is being or was taken in response to your text.

Will you they me back?

BTP will not call you unless they have agreed that with you beforehand.

How much will it cost to text?

Your mobile service provider may issue a small charge to text 61016. The exact cost will depend on your network and tariff.

Is the text number anonymous?

Yes, you can text anonymously if you wish. You don’t have to include your name or any identifying details in your text.

Will you try to identify me from my number?

BTP will not routinely conduct subscriber checks to find out who you are if you have sent a text anonymously, however, there may be occasions where this is necessary.

Can I text police in an emergency?

In an emergency always call 999. The 61016 text number is monitored 24/7 but there is no guarantee that your text will be received in time, so you should not use it to call for assistance in an emergency.

What about in places where there is no phone signal, such as on the Underground?

In these cases, there are other ways to get in touch with BTP: In an emergency, you should use the emergency handles on trains and help points on station platforms, or speak to a member of staff or a police officer.

If you are travelling through a station with wifi but don't have phone signal, you can also email BTP at first_contact@btp.police.uk.

If it is not an emergency, you should wait until you have a signal before texting.

In any situation, you can always speak to a member of railway staff or a police officer.
